"Came out the next morning and checked out the electrical outlets. The problem was we plugged in a coffee grinder and the cord flamed out. The electrician came out the next morning, because he knew this could be a big problem. After checking all the outlets on the circuit, determined it was an old, 30 year old coffee grinder. Our mind was at rest."

Electrical questions, answered by experts

Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

To upgrade electrical systems in older homes, you might need to reroute new wires with lath and plaster walls. That’s because it’s more challenging to get inside the walls of an older home compared to a modern home, which usually uses drywall. But there are easier ways to level up your electrical game in an older home. For instance, you can swap out an old furnace for a new electric heat pump, or you could use a heat pump for water heating.

No, you should always use proper electrical wire caps to safely cap off electrical wires. Electrical tape isn’t as durable as electrical caps and can deteriorate and separate over time, exposing the live wires. The only way to use electrical tape for this project is to wrap it around the caps themselves to reinforce them and create an even stronger connection, preventing an electrical emergency.

Multiple wire sizes are used for residential electrical purposes. While the most common sizes used in homes are 14 and 12 gauge, some appliances, such as stoves, electric water heaters, central air units, etc., may use larger gauge wire to accommodate their larger amperage. Typically, larger appliances require 10-, 8-, or 6-gauge wires.
