Field Wiring With Integral Controls
When heaters are furnished with
controls, make certain that the heater or
heaters do not exceed the lowest
amperage rating of the controls
furnished. For example, if a thermostat
and disconnect are furnished, the
thermostat is rated at 25 amps 240 and
277, the disconnect is rated 20 amps 240
and 277. Therefore, the combination of
heaters should not exceed 20 amps at
277 or 240.
