"I came to know Obez Electrical through a friend's referral back in.2016. Bryant presented himself very confident, professional, well communicative and so organized! The year 2016's project was to split 2nd unit in a multifamily setting with a separate electrical pamel, rewiring the entire unit, Bryant responded my service calls whenever there is a need, that's why whenever I need eletrical work, my 1st instinct is reaching out Bryant first. This year 2023 the past week I need electrical work in a new bathroom, with permit and it needs pass town inspection. Bryant was able to get through the challenges, cuz sometimes while on the job running the wires inside the walls, electrician could be presented with a variety of problems. Bryant has strong problem solving skills on site, being attentive to detail. Bryant has very good time management. He performed the job quickly, along with good planning skills, pretty much the same time as he first came to estimate the job. Needless to mention that Bryant is so patient and he educated me the electrical codes, which gave me a clear picture of what the requirements are amd how to comply with, I believe when next week I go to town and talk to the town electrical subcode official, we can be on the same page and talk in the same language, highly appreciated! Sincerely wish Bryant big success with his ecpanding business in commercial and residential. He can definitely charm you with his superior expertise! Look no further! I endorse him! If you need further details before you hire him, I can always be reached at [email protected] Residential lamdlord, Boonton Township, Bianca Zong"

Generator Install questions, answered by experts

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.
