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 swim 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 swim 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 swim spa occupants, but installed at least five feet from the
swim 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 swim 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 swim spa must be hooked up to a “dedicated” 240 volt, 50 amp
breaker and GFCI. The term “dedicated” means the electrical circuit for the swim spa
is not being used for any other electrical items (patio lights, appliances, garage circuits,
etc.). If the swim 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.
