Why this is a better choice for hot tubs:
Unfortunately, conventional load centers often perform unreliably
with hot tubs due to the phenomenon called errant tripping. This
false tripping is a great frustration to homeowners and electricians
alike, often incorrectly attributed to a problem with the spa, when
no problem exists.
Because of the reactive loads that spa motors present and the fact
that parts of the spa including ozonators may run on 120V, common
GFCI breakers sometimes react to a normal spa condition as if it
were a ground fault. They can be very unreliable.
Our GFCI Disconnect panel solves these problems. It's a dependable
ground fault detector designed just for hot tubs. The
specially-shielded GFCI prevents false tripping due to RF
interference. It is also engineered for low-voltage stability to
prevent tripping due to brownouts. If there is a ground fault, the
fast-acting GFCI instantly disconnects the lines.
Some jurisdictions REQUIRE the
installation of a 120V outdoor GFCI outlet, located 10-20 feet away,
enabling safe use of cord-connected appliances and equipment in the
Note: The bonus 120V branch circuit has its own 15A breaker, saving the expense of a separate wiring run for an outdoor
outlet. This alone pays for itself! Instructions
