Electrical questions, answered by experts

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

Unfortunately, a partial power outage without a tripped breaker often means you have a major wiring issue or that the breaker itself is going bad. When the power is out in one room but the breaker is not tripped, you need to call an electrician as soon as possible to identify the cause of the problem and repair it.

If you have a lamp that flickers or doesn’t stay on, it’s a sign that it’s time to rewire it. Additionally, it’s important to rewire antique lamps so they’re safe to continue using without the risk of an electrical fire. If the plug on your lamp is more than 15 years old or you notice poor performance like flickering, you should hire a lamp repair service to rewire it. If you’re upgrading the bulbs in an antique lamp from incandescent to LED or CFL bulbs, rewire it so it’s compatible with the modern bulbs.

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.
