Thanks for the heads up.

Boy, here's a hot one:
"Do not use the T-1 Circuit Breaker as a switch"

Name 2 boats that DON'T use circuit breakers for switches.....(c;

Mine doesn't. All loads are switched or controlled by other than the circuit
breakers.

Waste of switches. Breakers make fine switches. Don't know where
Larry is coming from on this one (as usual). The problem with the
T1 breaker is it is not idiot proof. If you hold the breaker in the on
position it holds the circuit closed rather then interrupting again like a
normal magnetic breaker will. I believe that the older thermal breakers
always behaved this way but I'm not sure. In any case, only a moron
would hold a breaker closed, but then again there seems to be an
unlimited supply of morons on boats these days

Doug,
All circuit breakers are not designed to be used as switches. Actually
they aren't guaranteed to work more than once, but I've know them to work
many times after being tripped repeatedly. They do make circuit breakers
that are intended to be used as a switch, I believe they have an "S"
designation on the breaker. If I were replacing circuit breakers I'd get
GFCI (ground fault circuit interrupter). They're a bit more but around the
water it seems like a good investment.

I assumed that the dicussion was related to breakers commonly
used on boats. ie Magnetic breakers these days. Breakers that
aren't guaranteed to work more than once would be pretty useless.
I think they are traditionally known as fuses GFCI breakers
are for AC. The T1 breaker that started this thread is for
12 VDC.

Doug,
Thanks for the correction, I was referring to AC breakers. Although I
wasn't aware there are specific breakers for DC. In machine control we don't
have breakers that are specific to DC or AC. 10 amps is 10 amps regardless
if it's AC or DC. I believe the breakers I'm familiar with are bimetal in
nature, if the amps pulled go over their rated value, the bimetal strip
heats up to the point it trips the breaker. The bimetal strip is a bonded
piece that has one type of metal on one side and a different type on the
other. The metals have a different rate of expansion as it heats up from the
current passing through it bends in an arc. If it bends far enough it trips
the breaker. As now the current is stopped, the bimetal cools allowing the
breaker to be reset.

Larry,
They do make circuit breakers intended for switch duty. If I recall
they're a "S" label on the circuit breaker.
