I went on a service call for no power to a moba home.
Custumer said he was outside when his wife reset the circuit breaker,which tripped every now and then,noticed a flash each time at the foundation vent.
It was one of those #$@!^%$ connector!!
The thing failed and each time they had reset it,it started a small fire and burned itself out. Very bad idea to use these.My opinion.
These remind me of those multi splice things some guy showed a few months ago for doing fast wiring. a real joke.
my 2 cents
