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).

SY2DLED-surge-protection-device

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.

Lightning & Surge Device 10651/LED

Lightning Protection – Product Focus – 10651/LED

Last week we discussed lightning protection being mandatory if the building is fed by over-head lines or it has external lightning protection. To follow on from that, in this week’s blog we will be talking about a specific device, the 10651/LED.

Why It’s Installed:

For those that missed our last blog, here’s a quick re-cap on why Lightning protection is installed.

When lightning hits external lightning protection (or over-head power lines) the lighting travels down the cable to the main incomer of a building. Although external lightning protection is earthed, only 50% of the total voltage from a lightning strike will go to earth and the other 50% (possibly up to 100Ka) will travel across the cross-bond on to the incoming panel and out on to the electrical circuits in the installation. This creates a massive risk to the property and to any life inside.

What Is It:

The 10651/LED is a three-phase lightning and surge combined device. This means that it not only protects against lightning strikes, it will also take any surges out of the electrical system. The 10651/LED is a large device (about 8 module width), which contains all the necessary components to ensure that the electrical system is safe from over-voltages and lightning strikes.

How It Works:

As we discussed last week, the lightning will travel down the copper tape (or over-head cable) and on to your distribution board. With the 10651/LED being so big, it is usually mounted in to an enclosure next to the main panel. When the device detects the spike in the system (whether Lightning or a surge), it directs the spike down to earth and re-sets itself. This device works in about 25ms, which is much faster that the RCD will detect anything, meaning that the breakers wont trip and the electrical supply will continue un-interrupted.

How It’s Installed:

As I previously mentioned, the 10651/LED is very large and usually is mounted in an enclosure next to the board, this needs to fit as close to the main switch as possible. From an existing three-phase breaker in the board, take your live cables in to the top of the device. Take a neutral cable from your neutral bar to the neutral terminal on the top of the device. Finally take an earth connection from the earth bar to the bottom of the device, for this connection the cable needs to be less than 50cm in length.

Lightning & Surge Protection; What is Mandatory?

It’s all very confusing when it comes to trying to work out what’s mandatory and what’s a recommendation when it comes to lightning & surge protection. This week in our fortnightly blog we decided to try and make it all a bit clearer for you.

What is mandatory?

 

Lightning Protection

Lightning protection is mandatory in certain circumstances;

  • If the building has external lightning protection already installed (copper tape and earth rods)
  • If the building is fed by overhead power lines

Why?

  • When external lightning protection is fitted: When lightning hits the external protection it travels down the copper tape to where it will be cross bonded to your incoming panel, where it connects with the earth. The reason for the mandatory requirement of lighting protection, is that only 50% of the lighting impulse will go directly to earth, the other 50% will travel through the cross bond on to the incoming panel and out on to the electrical circuits in the installation. This creates a massive risk to the life and to the property in this installation.

 

  • When the building is fed by overhead power lines: When lighting hits the power line, we have the same problem as with the external lightning prooverhead power linestection. The lightning impulse will travel down the power line directly on to the incoming panel, where again it will travel out on to the electrical circuits in the installation.

It is more common to see church’s, schools and hospitals with external lightning protection fitted, as these are classed as high risk buildings, especially with them being public places and in most instances tall. It is less common to see domestic dwellings with external lightning protection, however it does happen occasionally. It is more common to see a domestic dwelling with overhead power lines feeding the property.

Surge Protection

Surge Protection, as in type 2 and 3, are not mandatory, although they are strongly recommended it is not a requirement to have them fitted and your electrical system will still come up to standard without them. In our last blog we discussed the reasons why you would want to fit surge protection in your own home.

I hope this has made it a bit clearer for you, if you need any more advice on what sort of protection you need to be either fitting or recommending, please give us a call on 01484 851747 or you can send us an email through our contact form.

Why should you fit a surge arrester in your home?

Domestic surge arrestors are not mandatory, so why are so many people now fitting them?

The reason is money. The cost of a domestic surge arrestor such as our SY2-D is negligible compared with buying a new TV or replacing the electrical items in your house. Do a quick mental calculation of how much your electrical items are worth, your TV, washing machine, cooker, fridge and not forgetting all of the things you plug in to charge, such as phones, tablets and laptops. Now you can see how that bill would quickly mount up if your home was effected by surges.

Surges occur in every electrical system, they can come from your mains power, turning lights on or turning on large electrical items (such as a washing machine). Unlike lightning damage, Surge damage isn’t as easily seen, it won’t be anything dramatic like blowing up or setting on fire as can occur with lightning damage. Surges just slowly degrade all of the electrical components in your electrical system, which will shorten the life span of your electrical items. A TV that should last 5 years could only potentially last 2 years, if it’s seeing continuous surges.

trailing lead surge protection

Many people say “I don’t need to worry about surges, I use those surge protection trailing leads”. The problem with using these trailing leads as your only form of surge protection is that you don’t plug everything in to them, even the most safety conscious person would not think of plugging their washing machine or fridge through a trailing lead. When you start looking at how many of these trailing leads you would need to protect your whole house, can you imagine how much that would cost? Obviously it would be less than replacing all of your electrical goods, but still expensive, especially when you consider that the majority of surge protection trailing leads sold have little or no information on how they actually work or whether they comply with any sort of standards or regulations.

SY2DLED-surge-protection-device

The most efficient and cost effective way to protect a domestic property from surges is a domestic surge arrester. This can be mounted inside (or next to) any consumer unit, its easily wired in with a parallel connection to an adjacent breaker, a connection to the neutral bar and a connection to the earth bar and that’s it, your whole installation is protected from surge’s.

At only £56.44 each nett, the SY2-D provide a complete surge protection solution to your domestic installation for a great price!
