Electrical Connections - Bradford White RE2H50S 1NCTT Series Installation/Operation Instruction Manual

Electrical Connections

A separate branch circuit with copper conductors,
overcurrent protective device, and suitable disconnect must
be provided by a qualified electrician. All wiring must
conform to local codes or latest edition of National Electrical
Code ANSI/NFPA 70.
The water heater is completely wired to the junction box at
the top of the water heater. An opening of 1/2" electrical
fitting is provided for field wiring connections. The voltage
requirements and wattage load from the water heater are
specified on the rating label on the front of the water heater.
The branch circuit wiring should include either:
1. Metallic conduit or metallic sheathed cable approved
for use as a grounding conductor and installed with
fittings approved for the purpose.
2. Nonmetallic sheathed cable, metallic conduit, or metallic sheathed cable not approved for use as a
ground conductor shall include a separate conductor for grounding. It should be attached to the ground
terminals of the water heater and the electrical distribution box.
To connect power to the water heater:
1. Turn the power OFF.
2. Remove the screw(s) holding the junction box top cover.
3. Install L1 to L1, L2 to L2, and ground to the green ground wire connected to the bottom of the junction
box.
Note: Install electric connections according to local codes or latest edition of National Electrical Code
ANSI/NFPA 70.
Proper ground connection is essential. The presence of water in the piping and water heater does NOT
provide sufficient conduction for a ground. Nonmetallic piping, dielectric unions, flexible connectors,
etc., can cause the water heater to be electrically isolated. Do NOT disconnect factory ground.
The manufacturer's warranty does NOT cover any damage or defect caused by installation, attachment or use
of any type of energy-saving or other unapproved devices into, onto, or in conjunction with the water heater.
The use of unauthorized energy-saving devices may shorten the life of the water heater and may endanger life
and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of
such unauthorized devices.
If local codes require external application of insulation blanket kits, the manufacturer's instructions included
with the kit must be carefully followed.
Application of any external insulation, blankets or water pipe insulation to this water heater will require
careful attention to the following:
• Do NOT cover the temperature and pressure-relief valve.
• Do NOT cover access panels to the heating elements.
• Do NOT cover the electrical junction box of the water heater.
• Do NOT cover the operating or warning labels attached to the water heater or attempt to relocate them
on the exterior of the insulation blanket.
• Do NOT block the air inlet/outlets in the top covers or rear of the unit.
Note: This guide recommends minimum branch circuit sizing based on the National Electric Code. Refer to
wiring diagrams in this manual for field wiring connections.
