"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 ."

"From start to finish, Best Quality Electric delivered an exceptional, white-glove experience. The process began with a dedicated consultation that was educational, detailed, and thoughtfully planned—setting a clear vision before any work even began. The following day, the team arrived precisely on time and immediately demonstrated a level of professionalism that is rare to find. Shoe protection was used, and every floor and piece of furniture was carefully covered. Their respect for the home was as impressive as their craftsmanship. Watching the two electricians work was remarkable. They operated in perfect sequence, anticipating each other’s next step, covering every single detail with precision. Not one question went unanswered—each was met with patience, clarity, and deep expertise that inspired complete confidence. Best Quality Electric truly lives up to its name. This is not just electrical work—it’s a refined, high-standard service experience. Bold, meticulous Toptier work!"

I have never before seen the wires so neat and organized as I did after he was finished with my job. I will only hire PKJ for all of my future electrical needs. Thank you again for such a wonderful experience."

Electrical questions, answered by experts

For many homeowners, sheds are more than storage spaces for tools or lawn care appliances. If you’re thinking about building a work space outdoors or could make your life simpler by running electricity to a spot that’s closer to your yard, it could absolutely be worth the cost.

No, both switches do not need to be on for a 3-way switch to work. When the two switches are in opposite positions, the circuit is open and the light is off. Flipping either switch closes the circuit and turns the light on. So, either switch can turn the light off independently, and both switches do not need to be in the same position for the switch to function.

The number of outdoor outlets that can be on one circuit depends on the circuit's capacity and the electrical load of each outlet. Outdoor outlets should ideally be on a dedicated circuit that is not shared with other outlets, and each outlet should be rated for at least 15 amps. A circuit rated for at least 20 amps is recommended. It’s important to use GFCI protection for all outdoor outlets to prevent electrical shocks. Overall, it's crucial to avoid overloading the circuit and take necessary safety precautions.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

A GFCI outlet can be 15A or 20A. The average American home power outlet is 15A.
