![]() Larger image | Fuseholder holds fast-acting or slow acting fuse If load rating of circuit cannot exceed strict limits, then choose fast-acting fuse. Fuse protects all wires in the circuit Hot wire from breaker is also protected by fuse Timer shown is GE 15070 in-wall analog timer Timer require Neutral wire to operate analog timer dial When using ordinary switch, the white neutral wire does not connect to switch as illustrated See timer How to wire timers How to set analog timers Illustration shows contactor Contactors can control heavy Loads like water heater, motors, etc. Magnetic Coil is activated by timer or switch. Coil pulls down on contact points. When coil is deactivated, a spring pushes contact points apart. Contact points open and close circuit. See contactors |
![]() Larger image | Use fuseholder to tap smaller gauge wire into larger wire. Fuse is not same as GFCI. Both fuse and GFCI react to a short. GFCI will trip instantly when short to ground is detected. The action is instantaneous, and will save a life when power suddenly flows to ground. Fuse is different. Fuse reacts to buildup of heat. Open short will cause massive flow of amperage that will heat the fuse and trip the fuse. But the process is not instantaneous. |
