Electrical Connections - Bradford White ELECTRIC WATER HEATER Instruction Manual

Electrical Connections

Before any electrical connections are made, be sure the water heater is full
of water and the manual shut-off valve located in the cold water supply line is
open. If the heating elements are not completely immersed in water at all
times, they will be damaged (burned-out) if energized for even a short period
of time. There is no warranty for burned-out heating elements. Before
proceeding verify a correct electrical connection has been made by checking
the rating plate and wiring diagram. The temperature-limiting device is of the
manual reset, trip-free type and has been factory installed to interrupt all
ungrounded power supply conductors in the event of thermostat failure.
The plumbing supplier in your area ordered this water heater wired at the
factory to comply with existing area codes, but local utility codes may require
or allow other circuitry. Consult your local power company to determine the
correct electrical hook-up in order to meet local utility and building codes and
in order to obtain the most economical rates. All electrical connections to
elements, thermostats, and terminal block have been made at the factory.
DO NOT alter any of the internal wiring. Wiring connections may loosen
during shipment. Check all connections for tightness.
To make the wiring connections to a power supply, follow the steps below.
A) Remove the control box cover panel.
B) Bring the power leads from an adequately sized fused disconnect switch
(not furnished with the water heater due to varying state and local codes)
and connect to the terminal block. Consult your local code and/or utility
authority about the correct wire size for the length of the wire required in
this installation. Longer wire lengths will usually require larger wire size.
C) This water heater must be properly grounded. A ground connection is
provided for connection to a properly sized ground. (See wiring diagram
for minimum required ground size. Wiring diagram is located on the
inside of the element cover)
D) Replace the control box cover panel.
