ELECTRICAL REQUIREMENTS

All Models
Note: Electrical requirements by model is shown in Model Specifications. Only electrical configurations pertain-
ing to the models referenced in this manual are shown.
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORMATION
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 codes regulated by the authority
having jurisdiction at the time of installation.
These connections must be made in accordance with the wiring diagrams found
inside the control box and in this manual. This equipment has been designed to
operate on and requires 230V, 50Hz service. Make sure that power is not applied
while performing any electrical installation. A bonding lug for bonding copper wire
has been provided on the electrical equipment pack to allow connection to local
ground points. The ground wire must be at least 8 AWG (8.36mm2 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. The supply wir-
ing to the spa must utilize a symmetrically grounded system. The spa must not be
wired to electrical systems utilizing no ground (IT) or TN-C grounding. Be sure
to have a licensed electrician examine and ensure proper grounding is provided.
See chart on next page for wire size conversion. All Master Spas equipment packs
are wired for 230 VAC only. The only electrical supply for your spa must include
a switch or circuit breaker to open all non-grounded supply conductors to comply
with BS7671 (or other local jurisdiction code or law). The disconnect must be
readily accessible to the spa occupants, but installed at least five feet from the spa.
Residual Current Device (RCD) must be used to comply with this manual, BS
7671, or any local electrical code or law requirements. A residual current is a cur-
rent leak from any one of the supply conductors to ground. An RCD is designed
to automatically shut off power to a piece of equipment when a ground fault is
detected.
Route the cable into the equipment area for final hook-up to terminals inside
the control pack or junction box. The spa must be hooked up to a "dedicated"
breaker(s) and RCD. 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.
