Putting in an electrical automobile (EV) charging level entails extra than simply connecting cables and establishing the charging unit. It requires cautious consideration of security measures, together with earth bonding. On this weblog put up, we’ll discover the importance of fuel and water earth bonding for EV charging level installations and why it’s essential to have these measures in place.
What’s earth bonding?
Earth bonding protects you and your private home by lowering the dangers of electrical shocks and electrical fires.
Bonding is the follow of connecting all uncovered metallic objects not designed to hold electrical energy in an space by utilizing a protecting bonding conductor. Connecting bonding wires to steel pipes, resembling your fuel and water pipes, reduces the voltage that may have been there.
Bonding is important in buildings with steel fuel and water provide pipes. It is because steel pipes have the potential to hold electrical currents from faults outdoors into your private home. That is very harmful and may result in all or some metallic objects in your house changing into stay, which may very well be deadly.
Why do I would like earth bonding?
Earth bonding is a necessary want of each electrical set up, not solely EV charger installations. In easy phrases, the operate of earth bonding is to stop deadly electrical shocks. As such, guaranteeing protecting bonding is in place earlier than an EV charger set up is significant.
Any certified and authorized electrician putting in an electrical automotive charger ought to observe the BS7671 electrical rules and be certain that bonding is put in to the water and fuel pipes.
The one exception the place bonding doesn’t should be current is that if the pipes that feed the fuel or water provide are plastic.
Why will we ask for pictures of the earth bonding?
Earlier than putting in an EV charger, we all the time ask for photographic proof that the water and fuel bonding is in place.
Having photographic proof lets us know that we will set up the EV charger safely and that we don’t want to put in the water and fuel bonding similtaneously the charger, which might add an additional value to the set up.
Learn how to examine if you have already got fuel meter bonding?
Fuel bonding could be recognized by trying in or across the fuel meter field for a yellow and inexperienced earth cable (see instance beneath). Normally, the fuel bonding cable is situated close to the fuel meter, clamped to a copper pipe. The bonding cable can typically be discovered contained in the fuel meter field itself or contained in the property, the place the copper pipe enters the home.
Alternatively, when you can’t present photographic proof, you might present us with a duplicate of your most up-to-date electrical certificates, and we will examine whether or not you will have bonding put in.

Learn how to examine if you have already got water bonding?
To search out the water bonding, you would want to search for the water cease cock in your property (the faucet the place you’ll flip off the water provide for the home). That is often discovered beneath the sink, and once more, we’re searching for a yellow and inexperienced cable (see instance beneath). This cable is mostly discovered connected to a copper pipe someplace inside a meter of the water cease cock / cease faucet.
Once more, offering us together with your most up-to-date electrical certificates lets us examine whether or not you will have water bonding when you can’t present photographic proof.

I can’t discover my fuel and water bonding. What occurs subsequent?
In the event you shouldn’t have plastic fuel or water provide pipes and can’t find the fuel or water bonding, we should assume that you simply shouldn’t have bonding in place.
As such, we’ll take extra fee for putting in the fuel and water bonding on the day of the EV charger set up. If the client doesn’t need to pay to have the bonding put in, we must abort the job for security causes, and the client could also be charged a charge.
If the bonding is in place once we get to your property, we will proceed with the EV charger set up at no further value.
I’ve fuel and water bonding in place. What occurs subsequent?
When you have supplied proof that the bonding is in place or that you’ve got a plastic service and don’t want bonding, we will set up the EV charger with none further prices.
Nevertheless, even when you’ve got supplied us with proof that the water and fuel bonding is in place, all our engineers will confirm that the bonding is appropriate after they go to your property. It is because they might want to be certain that the bonding is definitely there, is the suitable dimension, and has been appropriately related.
If our engineers determine any points together with your bonding, we might have to quote you further prices to repair these points. In any other case, we could also be unable to put in the EV cost level for security causes. However that is prone to be a uncommon situation.
Abstract:
To stop deadly electrical shocks and electrical fires, fuel and water bonding have to be in place earlier than putting in an EV charger.
Buildings with steel fuel and water pipes want bonding as these pipes can carry harmful electrical currents. If the pipes that feed the fuel or water provide are plastic, bonding will not be required.
Proof of water and fuel bonding is required earlier than an EV cost level set up to make sure electrical security and keep away from further prices.
Fuel bonding can often be recognized by a yellow and inexperienced earth wire close to the fuel meter, whereas the water bonding wire is discovered close to the water cease cock.
If proof of bonding can’t be equipped, it is going to be assumed that it isn’t in place, and on the day of your EV charger set up, we’ll take extra fee for putting in the fuel and water bonding.
If bonding is confirmed, the EV cost level could be put in with out further prices, however engineers will nonetheless confirm the bonding throughout the go to.
