Good evening forumist.
Apology in advance, the post is a bit lengthy and please don't cane me too much, am in learning process.
I did an EICR for a 4 bedroom bunglow, as part of learning curve I came across the attached CU
1. which doesn't have a busbar, MCB are link with 2.5mm2 wire from live terminal of 63A 30mA RCDs which are used as main switch, Is this acceptable, if not, what code would give?
2. The board is a hager frush 2 tier, 14 ways. The box is plastic with a metal door, to my understanding it is not AMD3 compliance what are your thoughts and opinions?
3. I understand TT system require RCD, for fault protection, can additional protection 63A 30mA RCD be sufficient for 3 functions (main switch, additional and fault protection) or should we recommend an additional RCD.
Kind regards
