circuit-breaker allegedly "getting more sensitive"

Former Community Member
Former Community Member
OK, usual caravan park issues with more pitches than incoming supply, so client has acknowledged this by installing 10 A circuit-breakers for each 16 A outlet. With 24 pitches on a presumed 80 A single-phase cut-out, he has got away with it..... so far, but he doesn't close for winter....


He has a few regulars that complain about the 10 A circuit-breaker being too sensitive so client believes them and has fitted new 10 A circuit-breakers ready for this weekend.


Considering that a 10 A circuit-breaker will run at 11.3 A continuously and 16 A for about 10 minutes, I'm more inclined to think that the "shed puller's" use of the 2 kW built in heater, 2 kW supplementary fan heater, fridge and domestic 3 kW kettle plus entertainment equipment are more likely....


But, has anyone carried out any tests on circuit-breakers to prove/disprove the alleged reduced rating? Or links to any such reports?


Regards

    Not exactly evidence, more just conjecture based on what is sometimes a simple remedy.  Typically these may be B type. Pitches are intermitantly overloaded now and again. With micowaves, plug in electric hob( to get value out of the hook up and save gas), then everything else, including the fan heater in the awning to keep the dog warm, enough of these on demand for a few seconds, is going to be 30 amps or more. Anecdotal, of course, but something that can alleviate the tripping issue, is to replace with a C type.
