"Great follow through, good pricing. The generator required several trips and follow-up items because it required different inspections. They did a great job at following up on these steps and the generator works perfectly. Since that time we called them for some smaller electrical jobs. They are very detailed oriented, an example would be that I gave what I thought I wanted and they gave feedback based on their experience showing a better way to do it. I welcomed this and was happy they suggested it."

Electrical FAQs, answered by experts

It's less expensive to run power overhead because it doesn’t require excavation, and the power cables are less costly. However, underground electric service is better protected from weather and general wear and tear, so it’s less likely to get damaged. When determining which way to run power, consult a local electrician to get an expect opinion.

Yes, GFCI breakers are required for all outdoor outlets. This code requirement applies to all outlets located on balconies, decks, patios, and other outdoor lounge spaces. In addition, outdoor outlets need to have watertight covers that provide protection when cords are plugged in. If you have an older home that may not be up to code, it's a good idea to also ask your electrician about adding GFCIs to some indoor areas. Kitchens, bathrooms, basements, and any other areas of a home that are commonly exposed to moisture should have GCFI breakers.

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.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
