ALL CASES MUST BE GROUNDED. The case data chart shows the electrical ratings for
your case. This is the same information that appears on your refrigeration nameplate. The case
data chart is located in Chapter 2.
Note: Fan motors must operate continuously and panel must be marked sufficiently to
prevent the fan motors and anti-sweat heaters from being turned off accidently. When
cases are multiplexed, add the total of these amperage values to determine wire size and
circuit protection. Anti-condensate controllers can be used to control the
anti-condensate heater.
On electric defrost models, the defrost heater amperages of all cases on the defrost circuit should
be added together, and if their rating exceeds the defrost time clock or condensing unit breaker
capacity, a defrost relay and circuit breaker must be employed and furnished by others. Make
sure that proper wire size and branch circuit protection are employed for safe operation.
Electrical Termination Location
All electrical connections are made in the electrical raceway (see following figure). The wires
are clearly identified for termination purposes as follows:
Electrical Terminations (Inside of Electrical Raceway)
1. Refrigeration fan motors are labeled with the numbers 3 and 4.
2. Lighting terminations are labeled with the numbers 5 and 6.
Installation of Electrical Wiring
The following figures are provided to give guidance on the installation and connection
