Dual pole 110 volt main breaker?

[WbSearch]

Just had our boat surveyed and have to install a dual pole breaker in the main
box to disconnect both wires the shore power supplies. I am unfamiliar with
any for 110 volt supply. The only dual pole breaker I am familiar with is for
220 volt, but the breaker "legs" wouldn't line up with the supply in the 110
box. Any suggestions? Am I missing something?

Most 110 volt systems are "Split Phase", meaning its actually two
separate 110 volt circuits coming in, or 220 across the hot legs.

Most breakers are designed to fit in one manufacturer of box only.
Who made the box your trying to put a breaker in?
Did you ask for a breaker for the brand of box you have at a electrical
supply house?. And in most boxes, the master breaker is larger and
not the same physical size as the individual circuit breakers.

The inspector probably was talking about a disconnect. This is made for
disconnecting the two different phases, or "legs" that supply 3-wire service
to all service entry panels ("breaker box").

The disconnect isn't located along side the other breakers, but up at the top
of the panel. You typically pull down on the handle to turn off all power to
the boat. It is rated like a breaker, in amps, and will shut off power if
there is a major short circuit in the panel itself, or is used to disconnect
power when someone is working on the panel.

If your panel has no location for such a disconnect, you'll have to either
replace the panel with one that does, or install a small box for the
disconnect between the breaker panel and the point where the electrical
service cables enter the boat.

Good luck,
