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 6 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 current fault is detected.

Power hook-up to the spa must be 240 volt 3 wire plus ground

(6 AWG copper).

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.
