Electrical Wire & Labels

An electrical wire label is a marker that can be placed on a wire for easy organization and comprehension. Our selection of Statistics Pocket Book (SPB) markers temporarily mark wiring equipment, such as

• Electrical Wires
• Terminal Strips
• Load Centers
• Alarm Centers

These markers are used to identify specific wires and cables on a do-it-yourself job, commercial, or industrial jobsite.

If your house is more than 40 years old and hasn't been recently renovated, it's time to check your electrical wiring.

Warning signs that you need to update your electrical wiring:

• Breakers that trip or fuses that blow repeatedly

• A tingling sensation when you touch an appliance

• Flickering or dimming lights

• A persistent burning smell from a room or appliance

• Warm, discolored, or sparking outlets

• Two-prong ungrounded outlets throughout the house

• No ground fault circuit interrupter (GFCI) outlets in kitchens, baths, and other areas exposed to moisture

The United States National Electrical Code requires a green or green/yellow protective conductor, a white or grey neutral, and a black single phase.

• Red wires indicate a secondary live wire in a 220 volt circuit.

• Red wires are used in some types of switch legs and in the interconnection between smoke detectors that are hard-wired into the power system.

• Green wires are used to indicate the grounding of an electrical circuit.

• Yellow and blue wires are used to carry power but are not for wiring the outlets for common plug-in electrical devices.

• White and gray wires indicate a neutral wire.

• Black wires are used for power in all circuits.
