"Highly recommend! Very professional, friendly, prompt! Great job, great guys. Always called and showed up as promised. Jim came to see the scope of work and discuss timing just a couple of days after we spoke on the phone. The job was done as scheduled and done perfectly. They were knowledgeable and efficient - replacing some old knob & tube wiring in a 150+ year old house; and adding some new outlets/switches where I wanted them. I will call them again when I need any electrical work done!"

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

"I have been searching for electrician to come out and fix our voice, Network, and camera lines for our small business. I searched for weeks and wasn't so lucky. I came across homeadvisor.com and saw Progressive Consulting. I gave him a call, 10 minutes later her arrived at my business. I explained what I wanted and he already knew what it would take. He gave me a quote 30 minutes later. Very affordable price for the work he provides. The next day at 9:30 am he came out and completed the job just as estimated nothing less nothing more. I would HIGHLY recommend this company to anyone looking for electrical work. Quality and affordable couldn't ask for anything else."

Electrical questions, answered by experts

Electrical fires are unique from other fire types because they have the potential to deliver electric shocks in addition to being on fire. Avoid serious injury from possible electrical emergency situations by avoiding the use of water, foam-based fire extinguishers, wet-chemical fire extinguishers,  flour, or baking powder to put out an electrical fire. 

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

How often you’ll replace your electric meter depends on what type of meter you have in your home. Induction meters can last around 10 years, while static meters will typically last around 20. If you’re unsure which kind of meter you have, a call to your electric company can help ease your mind.

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

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.
