"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"

Electrical questions, answered by experts

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.

Unfortunately, a partial power outage without a tripped breaker often means you have a major wiring issue or that the breaker itself is going bad. When the power is out in one room but the breaker is not tripped, you need to call an electrician as soon as possible to identify the cause of the problem and repair it.

You can reset a breaker several times, but it’s bad for the breaker. Resetting the breaker too many times in a short period can make it overheat and cause damage. That’s in addition to the damage that the multiple overloads do to the circuit. If a breaker is tripping every few minutes, it’s far better to leave it off and call an electrician for an inspection. This also decreases the chances that a short circuit or other issue could cause an electrical fire.

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.
