"Belki is one of the most honest people I have ever hired. He is skilled in all areas and does a beautiful job. He constantly measured and remeasured before completing. He told me when something wasn’t needed and adjusted the price accordingly. He cleaned everything after each job and disposed of all garbage. He takes great pride in his work. I highly recommend him"

Electrical questions, answered by experts

Three-way switches are only replaceable with three-way switches. A single-pole switch won't work if you replace one or more of a pair of three-way switches. By electrical code, three-way switch configurations are necessary at the top and bottom of a staircase between residential floors.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

It wouldn’t be abnormal to view all wiring as simply wiring, but wiring has different gauges and can handle different loads. When you’re wiring for 240V, you need wire that is rated at least 240V, but honestly it’s better to spend a little more and just buy 300V wiring. This ensures a margin of safety in case the wiring gets overloaded.

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. 

How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It’s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit.
