ELECTRICAL 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 electrical service 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.

Service to the spa must be dedicated 240V, 50A 3 wire plus ground (#6 AWG
copper with minimum #8 AWG copper ground).

Route service into the equipment area for final hook-up to terminals inside the
spa control system. 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.
