All electrical wiring
installation to be performed by a
qualified licensed electrician in
accordance with National Electrical
Code and Local Electrical Code.
Connect electrical
power supply to the power block only.
Do not connect power supply directly
to elements. Connecting power
directly to the elements may result in a
dry fire and result in elevated
temperatures and a fire hazard.
For 208V units do
not apply more than 218V service.
Use minimum 90°
rated insulated copper conductors
only, sized in accordance with
National Electrical Code and Local
Electrical Code for the current in
Ampere Chart. If allowed by codes,
NM cable may require a larger wire
size than as listed on the chart.
Connect suitably
sized equipment grounding wire to
ground terminal provided. Neutral
(white) wire is not required for 208V
and 240V units.
Provide suitable
over-current protection (fuses or
circuit breaker).
Provide a power
supply disconnect within sight of
the steam generator or one that is
capable of being locked in the
open position as required by code.
Wire size (AWG) is
based on minimum 90° C rated
THHN copper conductors. Refer to
the National Electric Code for other
types of conductors.
