Welcome to ElectriciansForums.net - The American Electrical Advice Forum
Head straight to the main forums to chat by click here:  American Electrical Advice Forum

3 people were discussing scheme membership and insurance and it sounded like eiher 'domestic installers,' or their insurance, does not cover work on 3 phase installations.
Some 6 months ago I was informed that all WPD supplies to new properties are to be 3 phase and this is now what is being planned for (presumeably because of the fact that gas is no longer going to be supplied to new estates + car charging etc).
Is this going to restrict who can work on new builds or are bodies such as the niciec going to have to allow their short course members to be let loose on pretty much anything?

a lot of insurers don't cover for 3 phase on PL policies, or they will charge extra premium. same with tools cover. most are happy to charge for tools cover, but when you read the small print, they are not covered on van between 9pm and 6am. i made sure my policy covered both aforementioned scenarios. just for info, i'm with insurance octopus and they were by far the best price for the cover provided.

Just because DNO are installing 3ph supplies doesn't mean all houses will be connected as 3 ph.
It will be WPD future proofing their own network, a lot of which is well over 70 years old.
And of course the Customer / Developer will have to pay the extra for the cable and cut-out.

And I'm sure all the Bodies could come up with a 3ph training / assessment course if their was anything to be gained from it.

There will be a 3 phase head, but I don't think there will be 3 phase meters going in.
Domestic installers will still be only working on single phase installations, as domestic equipment is still only 230v design voltage.

It would be too much to change something like that considering a lot of members of the public still insist on doing their own electrical work. Can't expect them to realise theres 400v present.

Can you link where this info comes from? re no gas supplies... it could be interesting reading

What’s so special about 3 phase? It’s still just just low voltage and already in loads of domestic installations
There is 3 Phase and real 3 Phase with switchgear hydraulic/non hydraulic etc etc the size of a small house.

Loads of houses already have 3 phase supply/meters/DB.
In large houses where the electrical demand is more than 80/100A the only real option is 3 phase to split the load.

With the idea of 2+ electric cars being plugged into the supply at 5PM, then the electrical demand is going to go up, and possibly 3 phase car chargers could become the norm?


I find it hard to believe someone can call themselves an electrician, and not be competent with a basic 3 phase supply and board.....

Any electrician, Electrical Trainee or not will understand the 230 line to neutral and 400 phase to phase....The general public may not understand, and it is a big change if it comes around for the majority of domestic installations.

So gas boilers and jobs are on the way out?
Should I cut my gas off now and go all electric?

The amount of wood burning stoves going in around here I think they may have a bit of competition. There is rumours that COAL is being burnt on some of them. Remember that? :)

I think that technology will be that using GPS etc the charging point will be turned on during dips/off-peak in a geographical area so a steady area load on the network is maintained.

Also Tel you only get the value of the tools at the time they were stolen.
