your answer makes the most sense too me. In the regs it does say its simpler to double it as its lower on the side of caution anyway. i dont have a cat 4 meter so i have no option.
After ive done my Zs test i recconect the main earth croc onto the neutral test l1, l2, l3 select highest reading...
am i correct in thinking for determining the PFC, you can do a PEFC test aand PSCC test and which ever one is highest you can double and choose to be your PFC also is it true for 3 phase that PSCC Is usually always higher?
Ive seen some people croc on to the earth and croc onto the neutral and...
No, B, C, D does not denote domestic, commercial, industrial, it denotes the tripping curve or how much inrush the MCB can tolerate be for tripping.
Your right but then from my hands on experience i know that i use b types in houses (6 amps on my smoke circuits, give me a good example of you...

a quick google says an average CO Detector uses 1 amp ish.
1.5mm cable is rated for 14.5a in my blue book nice bit of headroom there
since that CO that uses 1amp ish is no where near that its acceptable to use a 6amp breaker...
yeah i got a cheeky photo of the board its got a spur with a 3 amp fuse, its not a smoke its a hard wired CO Detector.
Also it wont let me onto dans account
and Im guessing it would be a 6 amp b type for that circuit
Are you 100% sure on that? In the candidate checklist i went through the second thing on the composite installation was selection of protective devices, so how are you proving you know how to do that if they just tell you on a wiring diagram?
Hi I want too do my AM2 In the future. I want too know the breaker selection for the circuits in the AM2, an acceptable answer (for me.) will be from a recent am2 Passee (successful candidates only.).
The circuits are as Follows:-
