230V / 50 Hz Electrical Installation - Coleman Roto Spa Owner's Manual

230V / 50 Hz Electrical Installation

All 230V spas must be permanently connected (hard-
wired) to the power supply. These instructions de-
scribe the only acceptable electrical wiring procedure.
Spas wired in any other way will void your warranty
and may result in serious injury.
This is the only acceptable electrical wiring proce-
dure. Spas wired in any other way will void your war-
ranty. See the wiring diagram on page 10.
The electrical wiring of this spa must meet the re-
quirements of any applicable local, state, and federal
codes. The electrical circuit must be installed by an
electrical contractor and approved by a local building
/ electrical inspector.
RCD and Wiring Requirements
Your spa will require either one 32 amp RCD or two
50 Hz Circuit Board Connection
Coleman Roto Mold Spa (online sales)
LTR50001136, Rev. A
16 amp RCDs, installed with three #10 AWG copper
wires.
The power supplied to the spa must be on a dedi-
cated RCD protected circuit with no other appliances
or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
When wires larger than #6 AWG are required, install
a junction box near the spa and use #6 AWG wire
between the junction box and the spa.
Wire runs over 26 m must increase wire gauge to
the next lower number. For example: A normal 50
amp RCD with four #8 AWG copper wires run over
26 m would require you to go to four #6 AWG cop-
per wires.
