[QUOTE="southsparks, post: 458086, member: 157"] Thanks for reply Evans. Although the breaker is a 20 Amp, I would have thought a 32 A would be OK. as circuit for some reason, is wired in 16mm SWA. There's lots of breakers on various sites, but they are all pre-used and would be same age as the one we have. As there is no way of knowing to what use it has been subject to, reckon it might be chancy to swop with the one we have in use. As no chance of getting an unused one, think I might tell client to carry on with existing one. I have similar problems with elderly breakers in the past, and have used contact spray to inside and operated breaker (without any load connected) and that usually does the trick. Any breaker that has not been operated in a long time, could lead to a loss of contact inside eventually. Last option might be to remove SWA from the dis-board and fit to separate breaker unit outside, which in my mind would always have been the right way to do it. That would be a summer job when heating finished with. Thanks for your advice, Southsparks. [/QUOTE]
