Is there not another 32A in the board you can swap with?
Discuss C40 rcbo on ring main changes to b32 causing nuisance tripping in the UK Electrical Forum area at ElectriciansForums.net
No this is an older board, the circuit I’m working on was put on a 40a type c breaker presumably to stop a b32 from tripping out which is what I tried putting the circuit on. Not the type of property you really want to dig into all other electrics in. One of them jobs I’m wishing I never started!!Is there not another 32A in the board you can swap with?
Wylex the other circuits are on mcb’s, I’m altering the circuit that had previously been put on a c40 rcbo with hopes to swap it to a b32, obviously I thought something would be wrong but all seems okay, insulation resistance is low but is satisfactory for age etc of install, no major loads on the circuit. Was marked up as laundry room (where I’m moving some sockets around etc but found out it also turns of power in a room on other side of property hense high continuity readings, zs would be okay for a b type breaker but to high for a c type but finding a fault in a listed house which is rather large with difficult clients is finding itself quite challenging!. Thanks for replyProblem is you have no idea why it was on a 40A type C. There isn't another 32A in the board, what make is it.
I tried putting it on a b32 same make rcbo and it was tripping every now and then, client said every 10 mins but when I go back it stays on fine the whole time I’m there, rather confusing…Problem is you have no idea why it was on a 40A type C. There isn't another 32A in the board, what make is it.
