Choose 1" THQL breakers or GE's exclusive 1/2" THQP circuit breakers (THQP are available for most load centers). When sizing a circuit breaker there are two main factors to consider: (1) the load’s current draw, and (2) the wiring’s current rating. " Circuit breakers used to switch high-intensity discharge lighting circuits must be listed and marked "HID. EntelliGuard G circuit breakers are the newest line of low voltage power circuit breakers (LVPCBs) evolved from the exceptional designs and practices of GE legacy breakers. Some say it is ok because the lights controlled on the switch are drawing less than 15 amps and the max load passing through the switch will never exceed its rating.
