When tradespeople come in to do emergency works and the customers are out or just not in at that time, gas companies will leave a card warning of the possibility of a dangerous situation you have without earth bonding.
Many people because of this are left unaware and exposed to possible electrical shock conditions,
Please now armed with this information use it to check for this when you go home and when you visit elderly parents or friends even or share this page with them.
What is Bonding?
Bonding is a way of reducing another possible risk – the chance that when there’s a malfunction or issue within your electrics you might touch two separate metal parts carrying different voltages, which could (again) give you a severe electric shock.
At Tack Electrical we make sure that any metal pipes which could come into contact with electrical wiring are connected to each other and to the fuse board. This means that if any live wire touches a metal pipe the fault current will flow to earth via our installed cables – as above – it will also trigger a fuse or circuit breaker and disconnect the supply until the fault is fixed.
To ensure this happens we will normally go to your boiler and connect the (earthed) mains water pipe to the other pipes that flow and return for your heating system, your mains gas supply and your hot water. Usually, this means we can do all the work in one place (unless plastic poly pipe has been used).
If you have a tin or cast iron bath we recommend connecting that to the towel rail and then to the sink supply pipes.
Bonding is particularly important if you have an older type of fuse board!
Why do earthing and bonding need to be checked?
If you are having an alteration of addition made to your electrical installation, your electrician must check (as well as other things) that the earthing and bonding arrangements you have are up to the required standard.
This is because the safety of any new work you have done (however small) will depend on the earthing and bonding arrangements.
