Electricity: Wire Strippers

Nearly every cable or wire has some form of sheathing to protect it and keep it separated from other wires. Specialty tools allow you to strip sheathings quickly and with less chance of damaging the wire inside.

Are you looking for home electrical items -- such as switches and fuse boxes -- or parts and accessories for ones you already have? Try our dedicated electrical supply pages here:

Volt-Ohm Meter

Using a Volt-Ohm Meter

Be safe: read the owner's manual carefully to avoid damaging your multimeter. Rotate the switch to select the proper test function, such as volts, amps or ohms, before you start testing. Select a voltage or amperage range that's higher than the top value you anticipate testing.

(Top image) Use the resistance, or ohms, function to test switches. An "infinity" reading may indicate a defective switch.

(Bottom image) Touch probes to heating element leads. Compare the appliance specifications with the resistance readings in ohms on your multi meter.
