Things To Know Before Wiring Your Home


The Basics of Home Electrical Wire 

Before we plunge into the sorts of electrical wire, there are some basic terms, naming, and coding you should think about. Understanding these can make your outing to the tool shop that much simpler. To Know about the cable prerequisite at your home you can attempt and get the perfect wire size for your home. 

Cable Versus Wire 

The terms ‘cable’ and ‘wire’ so frequently utilized interchangeably that you may believe they’re something very similar. In any case, they’re most certainly not. 

Electrical wire is any material that conducts electricity. They’re the individual conductors inside a jacket. They’re either protected or exposed. 

A cable, then again, is the combination of two or more wires. These wires are collected together with a solitary jacket. 

Cable-Sheath Color Coding 

The external sheathing of cables is color-coded. Cables are color-coded to enlighten you concerning the size of the wires inside the cable. The color code likewise indicates the cable’s amperage. 

The following are the color and their associated size and amperage: 

  • Black. 8 or 6-gauge wire, 45 or 60 amp circuits 
  • Orange. 10-gauge wire, 30-amp circuit 
  • Yellow. 12-gauge wire, 20-amp circuit 
  • White. 14-gauge wire, 15-amp circuit 

Dim cables are underground feeder (UF) cables. All UF cables are dim. So as to know the gauge of the wire and the circuit data, you’ll need to check the cable-sheath naming. 

What’s more, cable-sheath color coding is a generally new advancement in the electrical business. It wasn’t introduced until 2001 and companies aren’t committed to utilizing it. Thus, you ought to consistently check with the manufacturer if the color coding complies with current guidelines. 

Wire Color Coding

Not at all like cable-sheath color coding, wire color coding is standard for all conductors. Home electrical wire is typically constrained to the accompanying colors: 

White. This is an impartial wire. It’s liable for completing a circuit via carrying the current back to the board. 

Black/Red. These are hot wires. That implies that they carry electrical current from the board to a device. The device may be a receptacle, light installation, switch, or an appliance. 

Uncovered/Green. This color code indicates ground wires. A ground wire comes into play when there’s a ground issue. These wires create a way for the current to come back to your home’s breaker, blow a wire, and cut off electricity. 

There are other colors of wire however there are the most common ones you’ll discover in your home. 

Recognizing what each wire speaks to can assist you with seeing how the different wires in your home contribute to your electrical framework. 


The two wires and cables use naming to educate you concerning the wire size, the material, the number of wires inside a cable, the sort of protection, and other special evaluations. The marks are imprinted on the wire protection or on the external sheathing of a cable. 

Wire Size 

The size of the wire alludes to the measurement of the conductor itself. It’s managed by the American Wire Gauge framework. More or less, the little the wire is, the bigger the gauge. 

It’s basic that the size of the wires you choose matches the amperage of the circuit. On the off chance that they don’t match, the danger of short circuits and flames is extraordinarily increased.
