ELECTRICAL INSTALLATION REQUIREMENTS
For All Models Except TS 120

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 (unless local
or state codes require a heavier gauge 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 wire.
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.
