When planning the electrical layout for your shop, make sure that outlets for power tools and lighting fixtures are on separate circuits.
Unless your shop has bright windows or your lights are equipped with battery backups, include at least two separate lighting circuits in your electrical layout. In the event one circuit is disabled, the lights plugged into the other circuit will still work.
Place outlets close to the eventual location of the tools they will power; distribute outlets all around the shop to allow for future tool acquisitions.
Avoid locating outlets on the floor; they will eventually become filled with sawdust and be a fire hazard.
Avoid plugging tools into one outlet using an octopus adapter; this can overload your electrical system, and is a sign that the wiring of your shop is inadequate. Upgrade the system by installing new outlets and wiring them to a separate circuit on the service panel.
Protect any new outlet in a garage or basement by installing a ground-fault circuit intenupter (GFCI).
Never work on the wiring of the service panel; entrance wires may remain live even when power is shut off at the main circuit breaker or fuse block.
Make certain that any new circuits or service sub-panels installed in your home or outbuilding are grounded to the main service panel. Individual outlets must also be grounded.
Do not take off the cover of the service panel.
Never work on your wiring in damp or wet conditions.
Do not touch a metal faucet, pipe, appliance, or other object when working on your wiring.
Never splice a power cord or an extension cord, or remove the grounding prong from a three-prong plug.
Use an extension cord to supply electricity to an area only temporarily-not as permanenl wiring.
Never run a power cord or an extension cord under a rug, mat, or carpet; do not fasten the cord using tacks, pins, or staples.
Never replace a blown fuse with one of higher amperage; do not use a penny, a washer, or foil as a substitute for a fuse.
If a circuit breaker trips or a fuse blows repeatedly, check for a short circuit, and determine whether the circuit is overloaded.
