I would definitely change to 16 A Commando sockets with Isolators. Fixed load so short circuit protection only required. Swap the RCBO for a 32 Amp and make sure it's a "Type A" tripping characteristic. Not surprised it keeps tripping. I would put an a clip on ammeter on the cable, I think you...
If you are rewiring don't just do the usual 2.5mm for power circuits. Try to keep the cables out of the insulation. You will probably still need to wire in 4.mm to satisfy thermal constraint. Hope this is helpful.
Thank you for your reply Simon, good point about the DNO and 3 phase supply. I will ask my Customer to follow this up.
Although not correct and will still imbalance the neutral, the incoming cable is 3 core CNE. They have tapped off one of the phases twice on the main feeder cable outside of...
Hi all, I have a site where the network cable was damaged do DNO has provided 3no. 100 Amp Fuses. 1 Fuse on L1, 2 Fuses on L2. L3 is damaged in the road and not in service. I have looked at onboard charger diagrams of several vehicles. As far as I can make out the "3-phase" capable vehicles have...
Would any fellow electricians consider using an open PEN device to protect a metal trailer used as a "Canteen". It is likely to be often connected to TNCS (forbidden by 717.411.4) and placed on concrete which makes the use of TT and rod impossible. I can draw similarity to an EV charge point...
