"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

To check if doorbell wires are live, use a non-contact voltage tester. Hold the tester near the wires; if it lights up or beeps, the wires are live. Always ensure the power is off at the breaker box before handling any wiring. If you don't have a voltage tester, consider getting one or consulting a professional to ensure safety.

It’s recommended that you test GFCI outlets monthly with the test and reset buttons. At minimum, you should test GFCI outlets when entering a new season, or every three months. These are important home safety features that you should ensure work properly.

An electrician can handle wiring issues with the garage door opener, like faulty connections, circuit problems, or sensor malfunctions, but they’re not the right person to hire for mechanical repairs. Garage door specialists handle things like broken springs, tracks, and panels, while electricians step in if there’s an issue with power supply, motor function, or safety sensors that aren’t responding correctly.

To prevent a plug from overheating, always ensure that the electrical load connected to the plug does not exceed the plug's capacity. If the plug feels hot to the touch or emits a burning smell, immediately shut off the circuit breaker and unplug all devices from the hot outlet. Prevent electrical fires by avoiding using extension cords or adapters with the plug, as they can cause it to overheat due to increased resistance. Additionally, ensure that the plug is properly inserted into the outlet and that the outlet is not damaged or loose. 

If wiring in a relatively modern home is damaged due to sudden events like a fire, a tree falling into the house, or a flood, then homeowners insurance is very likely to cover the cost of replacing the wire.

However, if it’s determined that wiring failed or started the fire because of age, neglect, or not meeting current electrical standards, then insurance won’t be covering any replacement. Also, insurance policies may charge more for particularly old kinds of wiring like aluminum wiring or deny applications altogether.
