9. Electrical Power
9.1 Electrical Recommendations
WARNING
To avoid serious injury or even death, follow all applicable
local, state, and national regulations, mandates, and
building codes for guidelines to install the electrical
power supply.
Electrical code requirements are different in the USA and
Canada. Refer to and follow the local building codes, and the
latest edition of the National Electrical Code (NFPA 70) in
the USA, or the CGA C22.1 Canadian Electrical Code - Part 1.
For a single iN199 water heater, the circuit breaker(s) should
be at least 15 amps per circuit.
For multiple units, install an adequately sized circuit
breaker. Installing a separate circuit breaker for each unit is
recommended to isolate units during service or repair.
15 Amps
Single Unit
60 Amps
Four Units
Note: For an electrical wiring schematic, refer to “15.2
Complete Wiring Diagram (all models)” on page 51 for
additional information.
NOTICE
The electrical connections for the water heaters are
polarity-sensitive. Before connecting the water heater to
the power source, test the polarity of the electrical circuit.
9.2 Connection Instructions
1. On single-unit installations, make sure the electrical
outlet being used is wired with at least 12-gauge wire and
grounded with an appropriately sized circuit breaker. The
electrical power required for the water heater is 120V AC
at 60 Hz.
2. Remove the two cover screws and open the cover.
WARNING
To avoid serious injury or even death from electrical
hazards, an additional ON/OFF electrical junction box
should be installed near the water heater. This switch
allows power to be removed from the water heater prior
to service or in the case of an emergency.
3. Route a customer-supplied, appropriately-sized wire with
ground from an electrical junction box with an ON/OFF
switch through the back panel of the water heater. Route
the wire through the cabinet to the junction box.
4. On the opposite side of the block from the factory-
installed wiring, connect the white wire to the white
terminal, the black wire to the black terminal, and the
green ground wire to the green terminal (for each circuit).
5. If multiple units are being installed, refer to “13.
Connecting Multiple Units” on page 47 for additional
information.
