"Mike Connelly of Shamrock Electric Co. Coordinated the installation of my whole house Generac generator with PSEG long island and my plumber. He connected the automatic transfer switch and fully tested the system upon completion of the install. He has it set to run a test for 10 minutes once a week. My wife and I are extremely happy with the unit and the professional set-up by Shamrock Electric Company ."

Electrical FAQs, answered by experts

Depending on complexity and materials, costs range from $150 to $500 per fixture.

Yes, you can put a dimmer on a three-way switch, but it can’t be the same kind of dimmer you’d put on a standard light switch. A three-way switch requires a three-way dimmer. If two switches control a single or multiple lights, then you need a three-way dimmer. The type of light bulb should also be compatible with your fixture and dimmer.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

A two-way switch is also called a single-pole or single-throw switch. These switches only have an on-and-off function and only control a single light or series of lights wired together. A three-way switch has no “on” or "off” position and works with a second switch in the circuit to control a single light or light series from two locations.

Soldering is a reliable and durable way to connect wires, but it isn't the only method. Nowadays, professionals often crimp the connection instead—although this requires a higher degree of skill than soldering.
