ELECTRICAL REQUIREMENTS
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORiiIiATION
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 wits 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. The supply wiring to the swim spa must utilize a symmetrically grounded
system. The swim spa must not be wired to electrical systems utilizing no ground (M
or TN-C grounding. Be sure to have a licensed electrician examine and ensure proper
grounding is provided. All Master Spas equipment packs are wired for 240 VAC only. The
electrical service 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
(GFCO 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 swim 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 swim spa
control system. 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. 201901
