ELECTRICAL INSTALLATION REQUIREMENTS
HAVE YOUR ELECTRICIAN READ THE FOLLOWING
INFORMATION BEFORE INSTALLATION BEGINS
Electrical connections made improperly, or the use of wire gauge sizes for incurring
power which are too small, may continually blow fuses in the electrical equipment box,
may damage the internal electrical controls and components, may be unsafe and in any
case will void your warranty.
It is the responsibility of the spa owner to ensure that electrical connections are made by
a qualified electrician in accordance with the National Electric Code and any local and
state electrical codes in force at the time of installation.These connections must be made
in accordance with the wiring diagrams found inside the control box.This equipment has
been designed to operate on 60 HZ alternating current only, 240 volts are required.
Make sure that power is not applied while performing any electrical installation. A copper
bonding lug has been provided on the electrical equipment pack to allow connection to
local ground points.The ground wire must be at least 6 AWG copper wire and must be
connected securely to a grounded metal structure such as a cold water pipe.
All Master Spas equipment packs are wired for 240 VAC only.
The only electrical supply for your spa must include a 50 AMP switch or circuit breaker to
open all non-grounded supply conductors to comply with section 422-20 of the National
Electrical Code.The disconnect must be readily accessible to the spa occupants, but
installed at least five feet from the spa.
A Ground-Fault Circuit Interrupter (GFCI) must be used to comply with section 680-42
of the National Electrical Code. A ground fault is a current leak from any one of the
supply conductors to ground. A GFCI is designed to automatically shut off power to a
piece of equipment when a fault current is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground
(6 AWG copper). Route the cable into the equipment area for final hook-up to
terminals inside the control panel.
The spa must be hooked up to a "dedicated" 240 volt, 50 amp breaker and GFCI.The
term "dedicated" means the electrical circuit for the spa is not being used for any other
electrical items (patio lights, appliances, garage circuits, etc.). If the spa is connected to a
non-dedicated circuit, overloading will result in "nuisance tripping" which requires
resetting of the breaker switch at the house electrical panel.
