Wire nuts in DC? was (Re: Fried Combinor Box) [RE-wrenches]

[Todd Cory, Bald Mtn. Solar]

Was that copper or aluminum wire? I regularly find AL wire has "crept" away from
a connection. Sometimes I get service calls for nuisance tripping circuit
breakers and the only problem is a weak (loose) connection that is heating and
tripping the breaker.
