I don't think the owner would be too fussed which meter it comes off, but I would certainlt discuss it before making a decision.Which raises an important question - which metered supply is the EVCP to be connected to?
Yes, its for the owner. What do you mean 'landlords supply'? Actually, I may not be understanding your question properly. It is for the owner, but it will be used by the customers.Is the job for the property owner? If so, you could always install a small single phase CU as a 'Landlord's supply'. Doesn't seem to be one, from the photo.
I do understand safe isolation of 3 phase, but when you guys start talking about 'out of phase, star and delta etc' I am lost. If I don't understand something as basic as that I don't think I should be adding to the 3 phase part of it. However, it does sound as though a 3 phase EVCP would be a better option for the owner. I'll make him aware of that so he can look elsewhere if he chooses.Any spare ways on the MG board, just above the intake? If possible I would seriously consider fitting a 3ph EVCP if the facility is there for future expansion and rapid charging.
Three phase is easy enough to work on you just need to remember the full safe isolation process which has a few more steps than single phase.
3 Phase installations test to confirm that there is no voltage between:
- L1 and L2
- L1 and L3
- L1 and Neutral
- L1 and Earth
- L2 and L3
- L2 and Neutral
- L2 and Earth
- L3 and Neutral
- L3 and Earth
- Neutral and Earth
When energised you should see voltage between earth and neutral:
L1 - 230V
L2 - 230V
L3 - 230V
Line to line you should see:
L1 - L2 - 400V
L1 - L3 - 400V
L2 - L3 - 400V
To get single phase from three phase all you do is connect to one of the phases and use the neutral.
