ELECTRICAL INSTALLATION REQUIREMENTS
Permanently Connected Equipment Assembly with Pump(s), Heaters, Luminaine, Ozone, Spa Side
Control(s), Pump shut off device, and Audio/Video Components.
Note: Some of the above components may be optional or not available with every spa model.
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 Electrical 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 60Hz.
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 8 AWG copper wire and must be con-
nected 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-ground-
ed 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 sec-
tion 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 ground fault is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground (6 AWG copper)
8 AWG copper ground.
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.
