3 phase equipment in order.

[clarkey231]

Hi,

I’ve just joined the forum because I would like some help and info if possible on getting my already installed 3 phase supply connected. I have a connection date in 5 weeks and I need to have the equipment mounted and ready for that date. All things ‘downstream’ of the consumer unit can be finished later.

I’ll try to attach a pic of the incoming supply. If I could then get in order the stuff I’d need that would be great.

Thanks in advance,

Dave.

Do you mean a distribution board for them to connect to. If not decided just put in place a four pile isolator.

For clarification the garage currently has leccy fed from my house. This will be disconnected so the garage will have a seperate 3 phase supply. It’s mainly just for running a starter motor and alternator testing machine.

Are you an electrician?
3phase is very dangerous if you don’t know what you are doing with it?

Do you mean a distribution board?

Yes I think so. I’m doing zero wiring as I don’t know what I’m doing. But I can mount the ‘stuff’ that will be required so when they come and fit the meter they have something to connect it to. Or am I simplifying what needs to be done to much?

No and I stay well away from anything more complex the plugs or the odd light fitting.

Well if the existing supply is being ditched someone needs to get the board in and put in a temporary or permanent supply to the existing consumer unit so it can be connected up quickly.

Ok so is that the minimum I would need?
Ie supply, meter. Isolator?

That is not priority but could be sorted.

I’m not sure he means the house supply is being ditched?
I took it that he is doing away with supply in the garage?

I was going to disconnect the supply from the house and use the 3 phase supply for everything in the garage.

 

[clarkey231]

The house is staying on its original single phase.

Yep I misread it.

Unusual for a dwelling to have two separate DNO supplies there are implications for earthing. Can you show the other supply, same earthing systems will require bonding together and different systems is another issue.

So the minimum I need for connection to take place is a meter and a 4 pole isolator of the correct rating?

Mmmm well over my head now? I thought if the garage and house where completely separated it was ok earth wise?

We’ve just had an extension built and the sparky did mention all this but as I say I’m defo not a sparky and don’t understand.

You will need a four pole 100A isolator.
