Choosing The Right Wiring For Upgrading A Home's Electrical Systems

Construction & Contractors Blog

If you're upgrading your home's electrical systems you will need to choose the type of wiring that is installed, as there are more varieties to electrical wires than most homeowners realize. Wires work by carrying a certain number of amps, which refers to the amount of electrical power it can provide. Each type of electrical appliance and piece of equipment in your home will need a certain number of amps to operate. Consider a few tips on how to choose the right wiring.

1. Choosing amps

It might seem as if you should simply choose wiring that carries the most amps no matter the circuit, but this will mean bringing more power into your home than you need. In turn, your utility bills will be higher.

Instead, note the amps needed for common household applications. Lights are typically at 15 to 20 amps, and a hot water heater may need 30 amps. Most stovetops and ovens need 50 amps, whereas a furnace or central air conditioner will need 100 amps.

The wiring that goes to your breaker panels will typically need to be at 200 amps as these provide the power that is then spliced and fed through each circuit from the panel.

2. Note the colors

When you buy wires for your home you will notice that their covering is different colors. This is not to be decorative; black, blue and red wires are hot wires, meaning they are carrying the electrical power themselves. White insulation means the wire is neutral, and green insulation is for a ground wire.

Never rewire your home without understanding these colors as this can cause risk of electrical shock to any contractor who may work on the electrical systems in the future.

3. Understanding the codes

When you shop for wiring you'll notice letters on the side of the insulator. H refers to a wire being heat resistant, so this is best for the furnace and stove. W refers to the wire being designed for wet locations; you would use these in the bathroom and kitchen or for outdoors use. N refers to resistance to damage caused by oil or gas. This is best for a gas hot water heater.

Remember that if it gets too confusing when you need to choose wiring for your home's renovations or upgrades, it's best to call a contractor. Electrical systems need to be wired properly, not just so your electrical appliances can operate but also so that you reduce the risk of electrical fires in the home.
