ELECTRICAL REQUIREMENTS

ALL MODELS
NOTE: Electrical requirements by model is shown in Model Specifications. Only electrical
configurations pertaining 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 swim 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 (8.36mm
a heavier gauge 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
(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 swim 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 swim spa occupants, but installed at least five feet from the swim 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 current 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 swim spa must be hooked up to a "dedicated" breaker(s) and
RCD. 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.
