Hi all am checking something. Appreciate the help.
Am having a new 3 phase supply installed. BG are going to install the meters.
There are 5 meters in all to be in a cupboard at the front of the property (common area) to serve 4 units and a landlord supply.
The setup is that UKPN will put in the cutout.
We then put in a 3 phase to 6 way (single phase) Ryefield box, then a red link before each meter.
BG install each meter.
After the meter I was going to have a 100A switch fuse before 25mm SWA to each flat where each CU is situated.
All good right?
So the BG folks providing the meters say they will install a 100A DP isolator switch after the meter (and so I don’t need to have a switch fuse).
I’ve have told them (several of them) the CU (hence the length of the SWA) is some way from the meter (20+ feet).
Am I wrong? and that you can do without the switch fuse and just a DP isolator switch is enough?? I thought the switch fuse protects the SWA cable it’s not just for convenience of a visiting engineer (and we can’t rely on the main fuse for that).
BG outsource the meter fitting and so am going to confirm with IMServ but I don’t want to have the meter fitting refused on the day for not having the switch fuses in place.
Any thoughts?
