SECTION 5.Electrical Connections
WARNING
The appliance must be electrically grounded in
accordance with the requirements of the authority
having jurisdiction or, in the absence of such
requirements, with the latest edition of the National
Electrical Code, ANSI/NFPA 70, in the U.S. and
with latest edition of CSA C22.1 Canadian Electrical
Code, Part 1, in Canada. Do not rely on the gas
or water piping to ground the metal parts of the
boiler. Plastic pipe or dielectric unions may isolate
the boiler electrically. Service and maintenance
personnel, who work on or around the boiler, may
be standing on wet oors and could be electrocuted
by an ungrounded boiler.

5.1 Main Power

Single pole switches, including those of safety
controls and protective devices must not be wired in a
grounded line.
All electrical connections are made in the eld
wiring terminal strip, which is located at the right side
of the appliance.
NOTE: All internal electrical components have been
prewired. No attempt should be made to connect
elec-trical wires to any other location except the wiring
box.
5.1.1 Power Circuits
All Copper Brute II non-pump-mounted heaters
require a single 120-volt fused supply.
Pump-mounted Copper Brute IIs models 500-
1500 also uses a single 120-volt fused supply and
models 1750-2000 use two 120-volt fused supplies.
The installer can change the pump mounted
single service heaters to use a separate circuit for the
pump, if desired. Instructions to make this change are
found in Section 5.1.2.
Copper Brute II 500-1500 main power (L1, N1
& Ground) shall be connected to the three wires (10
AWG) supplied. Over current protection ratings can be
found in Table 10.
Copper Brute II 1750-2000 will require two 120-
volt fused supplies. Heater circuit can be identied
with 10AWG wires to include black, white and green
(all solid colors). Pump circuit can be identied with
three 12AWG wires to include a black wire with a
white tracer (stripe), a white and green wire.
5.1.2 Pump Circuit
Conversion to separate pump circuit will
necessitate removing the three jumpers within
the internal wiring of the 120-volt portion of the
heater (see Figure 13). Only do this with the power
disconnected to the unit.
To rewire the pump circuit, bring in another
120-volt fused supply (L2, N2 & Ground). Connect
incoming power (L2) to the main power switch using
spade (fork) terminal. From the other side of the main
power switch connect to the main terminal block using
a ¼" female insulated quick connect. This will be
the same position where the jumper had terminated.
Connect N2 and Ground to the main terminal block
using ¼" female insulated quick connect (refer to
Figure 13).
Ladder diagrams are shown in Figures 16
through 18, while wire diagrams are shown in Figures
19 through 21.

5.2 Temperature Control

5.2.1 Temperature Control Description
The eld wiring panel is located on the right
side of the Copper Brute II (shown in Figure 14).
The following components are connected to the eld
wiring panel:
Temperature sensor: The sensor supplied loose
