Electrical Requirements - Marquis 660 Owner's Manual

electrical reQuirements

It is the responsibility of the spa owner to ensure that all electrical connec-
tions are made by a qualified electrician in accordance with all national,
state, and local electrical codes in effect at the time of installation.
240 Volt
All connections must be made in accordance with the wiring diagram found
on the inside of the control box cover. Connections must be made with
copper conductors only – do NOT use aluminum wire. All conductors, circuit
breakers, and fuses and the GFCI must be sized in accordance to the total
amperage load as specified:
• Permanently connected (Hard wired).
• Rated 240V, 60Hz, 50A, three wires (#6 copper) plus ground (#8 copper),
[4 wires total].
• Circuit breaker or fuse size: 50A.
• A disconnecting means must be installed within sight from the equipment
and at least 5 feet (1.52m) from the inside walls of the spa.
• Connect only to a circuit protected by a Class A Ground Fault Circuit Inter-
rupter (GFCI).
• For units used in other than single-family dwellings, a clearly labeled emer-
gency switch shall be provided as part of the installation. The
switch shall be readily accessible to the occupants and shall be installed at
least five feet (1.52 m) away, adjacent to, and within sight of the unit.
• A pressure wire connector is provided on the exterior of the control box
to allow connection of a bonding wire to any metal ladder, metal wa-
ter pipe, common bonding grid (reinforced concrete slab, ground plate
beneath the spa), or any other metal within 5 feet (1.52 m) of the spa.
The bonding wire shall be copper and at least #8 AWG (8.42mm²), #6 in
Canada.
120 Volt
120 Volt spas shall be plugged into a properly grounded, grounding type 15
amp receptacle on a dedicated circuit. A dedicated circuit is a circuit with
no other components that consume power, such as lights, televisions, ra-
dios, computers, or other electronic devices. These could cause your spa to
malfunction by any of the following: unusual text on the control panel, slow
heating, poor jet action, tripping house breaker, or blown fuses. Failure to
follow these instructions could lead to premature failure of spa components
that would not be covered under the warranty. The dedicated circuit shall
meet the following specifications:

installation instructions
note: Ensure that a Ground Fault
Circuit Interrupter (GFCI) is properly
installed. Failure to do so may result in
spa malfunction or damage which is not
warranted. GFCIs are available from your
authorized dealer.
