"For the past 15 years Mike from Shamrock Electric has done extensive electrical work for two homes. He is personable, reliable, knowledgeable and fastidious. Recently he returned for a smaller job and completing a delicate onyx sconce installation with the same skill and expertise. I’m always confident that the job has been done right when Mike does my electrical work. I highly recommend him. He is a pro!"

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.

It’s not a good idea to mix LED and incandescent Christmas lights if you can avoid it. LEDs and incandescents can have significantly different electrical current needs. This difference can lead to a higher risk of problems and failure for both light strands. When possible, switch all your lights over to one kind or the other for the best results. Do not connect the different types of light strings to each other, and avoid linking them to the same circuit. 

Just like apples in a bunch, one bad outlet can cause other outlets to stop working. This is especially true if the outlets are connected in a series on the same circuit. When one outlet develops a fault, it can spread to every outlet downstream of the original.

Whether you need electrical upgrades depends on the electronics your game room includes. If your game room will have high-powered electronics, arcade machines, or a home theater, you may need to upgrade your electrical panel or add dedicated circuits. An electrician can assess your current system and provide an estimate for any necessary upgrades.

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.
