Knob-and-Tube Wiring Replacement in Newark: questions
Do I need a permit for knob-and-tube wiring replacement in Newark?
Usually, yes. New Jersey uses a statewide Uniform Construction Code, and electrical permits in Newark come from the city's construction code office. Electrical contractors are licensed by the state Board of Examiners of Electrical Contractors. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Newark?
If the work affects the meter or service, the electrician coordinates with PSE&G, which owns the meter and service drop.
Is knob-and-tube wiring illegal?
Existing knob-and-tube is generally not illegal, but it cannot be extended, and many insurers and lenders treat it as a reason to replace.
Can knob-and-tube be insulated over?
It is not recommended, and many codes and insulation programs prohibit it, because the wiring relies on open air to cool.
How do I know if mine is still live?
An electrician can test it. Many homes have a mix of active and abandoned knob-and-tube.
How long does replacement take?
From a few days for a small home with good access to a few weeks for larger plaster-walled homes.
