ELECTRICAL INSTALLATION REQUIREMENTS
14
DO NOT DIVE.
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 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 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.
