"Exceptional from the start! Scott responded in less than 24 hours after I requested a quote and was able to stop by and evaluate my project. His rates were more affordable than competitors. He communicated thoroughly, was highly professional, and his attention to detail was more than expected. He showed up on schedule and got the project done in a timely manner. I don’t know what more I could say, but I highly recommend. I will be using Scott for all future electrical work!"

"Grand Bay did a phenomenal job installing a new service panel in our home. The crew that they sent out were amazing. Not only did they install a new panel, sub panel and hot tub hook up, They also put in (6) GFI's and ceiling fan. We were so happy with the service we received and would recommend Bay Electric to anyone who needs an electrical job done right, these guys rocked it. Thanks to the entire crew and to Nick who put up with me making change after change. Thanks for putting up with me."

Generator Install FAQs, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
