Here are three circuits which can save time and prevent frustration. They go well with "Don't Blow a Fuse" by Ronald Newton (Nuts & Volts, August 2006, page 40). When I built his circuit breaker box, I added two test leads with insulated alligator clips for fuses in a fuse post holder.rnMy first circuit — shown in Figure 1 — is connected in the AC input of the equipment being tested, with S1 set to "lamp." Blown fuses in the equipment are bridged with Mr. Newton's substitution box (or replaced). If Lmp1 and Lmp2 are correctly chosen, new fuses will not blow, even with shorts in the power supply of the equipment.
