Update on our sponsored horse Teemo at Ravelrig RDA

2020 update on Teemo…

There was very little good news in 2020, but at Ravelrig they see their glass as always being half full. One of the positives coming from the COVID-19 lockdown was all the horses benefitted from being turned away in to the fields and allowed to be horses.

The enforced chill out time was particularly beneficial to Teemo who was still showing signs of the injury sustained 18 months earlier. After 4 months he was gradually brought back into work to build up strength and muscle and I am delighted to announce that Teemo appears to have made a complete recovery from his earlier injury.

Before returning to RDA work, training was carried out to give all horses new skills to deal with social distancing. They were led to the ramp for mounting and ‘parked’ whilst the leader stands back two meters to allow the rider to mount unaided or with the help of someone from their household, after which they ride unassisted or led from the end of the lead rope.

Additional training has been carried out for hoist mounting for less able riders to be mounted safely with minimum handling. For both exercises, Teemo has been an absolute star, if he didn’t do it right initially it was because he didn’t understand. He is now our first choice of horse for demonstrating the new mounting techniques to both riders and volunteers.

Teemo’s life is good right now. He is back in full work, he is ridden regularly in volunteer lessons under the instruction of a qualified coach, he hacks out at least once a week and he also carries out his duties as an RDA horse. Teemo is a big, gentle giant and would be sorely missed if he wasn’t with us.

SPD Training Academy

I am proud to announce that the team at Surge Protection Devices Ltd are launching an SPD Training Academy.

What is the SPD Training Academy?

The SPD Training Academy is a new addition to our website offering. We aim to provide attendees with up to date information regarding surge protection through our range of webinar sessions.

All of our webinars are completely free and we are CPD certified, so every attendee will receive a CPD certificate. All webinars are given by Kirsty Johnson, our technical sales director. Kirsty sits on the JPEL panel to assist with the wiring regulations, so is well placed to give training on Surge Protection to the latest regulations.








What topics are covered in the webinars?

SPD Ltd currently has the following courses available for immediate sign up:

Basics and the 18th Edition: This session is aimed at electrical contractors who may have limited or no experience with surge protection to give a basic understanding of what surge protection is and why we use it, through to how it works and where it needs to be installed. We will then cover the 18th edition guidance to finish off the session.

Apprentice: Introduction to SPD’s: This session is an apprentice only session where we will cover the fundamentals of surge protection to prepare apprentices to do the full basics and the 18th edition webinar (above).

Focus Training: Surge Protection Devices: These sessions are bespoke sessions for Focus Training learners, please contact your lecturer for further information.





Free CPD Training on Surge Protection: The Basics & Intro to 18th Edition

During these uncertain times, businesses are changing the way they operate in order to survive. We are exactly the same. We are a family owned and run company that strives to provide outstanding customer service at all times. We believe in a personal level of service at all times. We believe education is very important, especially when it comes to Lightning & Surge protection devices. They do say knowledge is power for a reason!

We are taking this time and opportunity to concentrate on on-line webinars focused at educating people from all over the country on lightning and surge protection devices.

In this 45 minute webinar we aim to explain the regulations surrounding the installation of surge devices, explain which device you need, and where to fit it.

We also open up the mic for a question and answer time at the end.

We have a range of dates and times to suit.

If you would like anymore information on these webinars, please contact Kirsty at kirsty@surgedevices.co.uk


Training – How to sell a domestic surge arrester…

This month we will be focusing on how to sell a domestic surge arrester. I wanted to start with the domestic market as it is generally more difficult to sell a domestic surge arrester than it is one for a commercial or industrial installation.

With a domestic installation according to the Regs it is only a recommendation that surge protection is installed, it’s not mandatory. So why do we need to fit them? I hear you all say. Well, its actually really simple… Every single household nowadays has some form of electrical equipment inside, whether this be just a kettle, microwave and a TV or on a much bigger scale, cinema room, LED lights and electronic gates, everybody has something of value to them that could potentially be destroyed by the effects of surges.

A lot of people know and use the trailing leads to protect 2-3 pieces of equipment, like a PC, laptop or a TV for example. These trailing leads only protect a few pieces of equipment at a time, unless you plug them into every socket in your house, which then gets very costly and looks messy. It is also impossible to fit them behind kitchen units to protect washing machines and tumble dryer’s. The only way around this dilemma is to buy and install a domestic surge arrester like our SY2DLED (pictured below).


This compact device combines double pole protection in a single module unit, which is easier to install in a domestic situation. It has an LED light on the front, which is a requirement of the Regs that all surge protection devices should have visual indication. Once this light goes out its time to replace the device, but these will typically last 10-11 years.

SY2D in consumer unit

To install the SY2DLED into a consumer unit just clip it onto the din rail or mount it in an enclosure and connect the device in parallel across the board. From the bottom of the device take an earth wire up to the earth bar. From the top of the device take a neutral wire up to the neutral bar. Also from the top of the device take a live connection to an adjacent breaker that’s already in the board. And there you have it, your surge device is installed and ready to start protecting your electrical items.

So how do I sell one of these to my customers? Like I said before this is the tricky bit, as it’s not mandatory. I usually start by asking the customer what electrical items they have in their own home and asking them to add up in their head roughly what its all worth. The trade list price is £70.55 and they typically last 10 years. This equates to roughly £7 per year to protect all your electrical items in your house. It will even protect your mobile phone when you plug it in at night to charge it. Plugging any piece of electrical equipment in without protecting it makes it susceptible to damage caused by surges.

Because technology is getting smaller but faster and more complex the manufacturers are using smaller micro-components, which are extremely sensitive to surges. When a piece of electrical equipment sees a surge it prematurely degrades the micro-components, so the piece of equipment wont last as long as it should.

This particular surge device is a perfect add on to those purchasing consumer units for re-wires or a new board fitting. We are very competitively priced and provide outstanding technical knowledge as well as offering FREE site surveys.

If you would like to know more about Lightning & Surges, how to protect your sensitive electrical equipment or learn more about how to sell surge protection then please get in touch with us and we can arrange a staff training session completely FREE of charge. You can either email me at helen@surgedevices.co.uk or call me on 07969919161 to book the training.

Surge protection and the 18th edition regulations…

Today I would like to talk to you about Surge Protection and the 18th edition regulations…









There has been a lot of noise in 2019 about the correct use of surge protection devices while conforming to the 18th edition so today I am going to go through the regulations and use my specialist knowledge in surge protection to explain when, where and how SPD’s should be installed.

In the regulations there are a few installations where surge protection must be fitted:

(Page 101, Regulation 443.4)

Where the consequences of over voltage could:

– Cause serious injury or loss of human life.

Here everyone always considers hospitals and doctors surgeries, where in fact this single line covers a lot of the installations that most contractors work on daily. Under this regulation, any board feeding emergency lightning or fire alarm panels must have surge protection installed. This is because if this equipment was to be damaged, it could mean a potential injury to people within the building.

– Damage of public services or cultural heritage.

For public services this could be anything from a train station to a library, or even motorway services. If it can affect a public service an SPD must be installed. For cultural heritage, this is to mainly protect important historical remains from potential damage, especially when dehumidifiers, or other critical equipment are used to prolong the lifespan of historical objects.

– Interruption to commercial and industrial activity.

This one we have just covered in our last article, but is pretty self explanatory.

– Could affect a large number of co-located individuals.

This could be anything from a school to an exhibition centre or even a block of flats. If electrical damage can affect a large group of people, then an SPD must be installed.

When applying these regulations, it is important to understand that the regulations are not retrospective, therefore will only apply if you are installing a new distribution board or making a significant amendment to an existing installation.

For all other installations, either an SPD is installed or there is a risk assessment which can be performed which will give you a risk level, to state if SPD’s are needed in that installation. I will go further in to the risk assessment method in our next article.

The exception is single dwellings, where an SPD can be omitted if the value of the installation is not seen as significant. This is not a very clear regulation. Essentially it means that the contractor must discuss with the installation owner whether they want an SPD installed or not. It is recommended that if you discuss SPD’s with the home owner and they decline to have them installed, that you get a paper confirmation of this, whether that is on the quote itself or in a declaration such as the document available through NAPIT. This will ensure that if any damage is caused in the future, which could have been averted through the use of an SPD, that the contractor will have proof that it was declined by the customer.

That is most of the regulations surrounding the use of SPD’s. The last thing I would like to mention is the mixing manufacturers regulation. Essentially, as an SPD is installed from an MCB and not directly on the busbar system, it does not affect the integrity of the consumer unit. Also as an SPD is a voltage detection device, it does not have a short circuit withstand capacity, such as an MCB, so does not require type testing to any specific manufacturer. With SPD installation, it is very important to keep the cable lengths as short as possible, so by installing the SPD in the consumer unit, you are keeping these cable lengths to a minimum. Therefore, any manufacturer who states that a contractor must use their SPD is using this regulation for commercial benefit, not to enhance the safety and integrity of our electrical systems, which is what BS7671 was designed to do.

Lightning and Surge protection in Commercial and Industrial installations…

Lightning and Surge protection in commercial and industrial installations









Following on from my previous post on 21st November about Lightning protection in domestic installations we move on today to discuss lightning and surge protection in commercial and industrial installations.

BS7671 states that Surge Protection Devices (SPD’s) must be installed where the consequence of an over-voltage could result in an interruption of commercial and industrial activity, which in most commercial / industrial installations will be the majority of distribution boards.

When considering which device to install, we need to look at where on the electrical supply you are working. If you are working on a main incoming panel, you will need to assess whether the building needs a combined lightning and surge device (Type 1+2+3) to protect against direct lightning strikes. As discussed in the previous article, only buildings which are either fed by an overhead power line or have an external Lightning Protection System (LPS) will need a Type 1+2+3 device, otherwise a Type 2 device is sufficient. If you are working on a sub distribution board that doesn’t feed any external circuits, the device you will need is a Type 2, which will protect against any transient over-voltages.

If you were looking at protecting a whole commercial or industrial installation, rather than just the board you are working on, firstly a device will need to be installed on the main incomer, then any sub distribution boards more than 10 meters away will need their own protection. Unfortunately, surge protection has a limited range of protection, which is limited after a 10 meter radius, and as surges are most often caused inside the electrical installation rather than transmitted from the main incomer, it is important to ensure that the devices are installed as close to the equipment you wish to protect as possible.

Lightning Protection in Domestic installations…

Lightning Protection in Domestic installations…

Following on from my post last week about surge protection in domestic installations today I want to talk to you about lightning protection in domestic installations.

Lightning Protection only needs to be installed on a domestic installation when the property is directly fed by over head power lines, or has an external lightning protection system (LPS) on the property.

Having an external LPS on a domestic property is rare, because the LPS system is designed to protect the physical building in a lightning storm. Most domestic properties are deemed not at risk from direct lightning strikes. The LPS is usually cross-bonded to the main incoming panel, so generally when an LPS is struck by lightning, 50% of the energy goes to earth through the earth rods, then 50% of the energy comes into the building via the cross-bond. Please see the photo below.








This is the same principle with overhead power lines, except as the L&N supply come directly in to your incomer, if the overhead line is stuck by lightning the whole lightning impulse is then transferred through to the domestic electrical system.

This is why you need to install a combined lightning and surge device (Type 1+2+3) on the main panel where the LPS system is cross-bonded to, or where overhead power lines are connected to the internal electrical system.

If there are any consumer units more than 10-15 metres away from the main incoming panel then a surge device (Type 2) will need to be installed. This surge device will be taking care of all the surges generated internally to the property.

Please note that a combined lightning and surge device (Type 1+2+3) will not only protect against direct lightning strikes but also internally generated surges too.
