whats best to do ?

advice on best way to solve tripping

i got a radial 16amp suppling a kitchen ( small ) ge series e 16amp mcb

got a problem with tripping when washer dryer is on then kettle is put on

i think overloading radial ( looking at kitchen there is only the washer & dryer on a socket and i think off hand 2 more double skts ) cooker on its own mcb

what would be best to solve this tripping would i swop mcb to a 20 amp or do i change to a c type 16 amp or is it better to make the radial into a ring ( latter maybe a problem as kitchen is tiled & finished )

cheers jon

What sized cable is the radial wired in??

Have you tested the circuit too?

Stick the current clamp on and see what it is drawing. dont overlook the chance of a dodgy MCB, but test the circuit properly before you start throwing parts at it. I would be surprised if kettle and washing machine would trip a b type 16a MCB under normal circumstances. The breaker should be able to handle about 5 times its rating for a good while before tripping in overload, certainly long enough for the kettle to boil.

Yeah my bets on the cable..Must be a fault (nail through cable etc) that's had time to suffer?

not yet it was one of those questions asked when i was leaving site after 8 hours doing the lights changing every sodding downlight in house for fire proof versions
i looked at board & sasw it was 0n a 16 amp supply , so guessed it was a radial suplying kitchen i told them to get a 20 amp mcb sorted and ring me ( as customer was adament to buy his own gear )

this was friday no call as of yet but they will as i need to go and test system as i worked in kitchen & bathroom i couldnt test the same day as it was late & the joiner wanted to finish loft boarding..
