Provided is a modular precharge circuit capable of rapidly recharging an equipment circuit path prior to insertion of a modular fuse or modular circuit breaker. The precharge circuit includes a switch to begin the operation of precharging, and a charge indicator to indicate appropriate charging has occurred. Charging occurs through use of a resistive network which receives an inrush current due to capacitance in the equipment circuit path. Once an equipment circuit path has been precharged to a desired level, a charge indicator signifies such charging is complete and the precharged unit is removed whereafter an appropriate fuse module and/or circuit breaker module is inserted. The precharge circuit further includes a fusing element and an alarm indicator wherein when the circuit enters a fault state such that the fuse is open, the alarm indicator signifies such a situation. Additionally, when the charging indicator verifies the charging element is not precharging the circuit to a desired level, an indication of a short exists.
