Why knob-and-tube wiring replacement comes up in Waterbury
Waterbury's hills are lined with triple-deckers and Victorians built when the Brass City's mills were booming, and knob-and-tube wiring is still common in Overlook, Bunker Hill and the East End. In a triple-decker, the work usually means three apartments and three sets of circuits, often done one unit at a time so tenants can stay. Stacked wall cavities, basements and attics give the electrician routes for new cable.
Connecticut's weatherization programs generally will not insulate over active knob-and-tube, which prompts many owners to replace it. Permits come from the City of Waterbury's building department, and Eversource coordinates service changes.
- Triple-deckers and multi-family homes often have separate small services, knob-and-tube or cloth wiring, and decades of add-on circuits.

Knob-and-Tube Wiring Replacement in Waterbury: questions

Usually, yes. Electrical permits come from the City of Waterbury's building department. Connecticut licenses electricians through the Department of Consumer Protection. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Waterbury?
If the work affects the meter or service, the electrician coordinates with Eversource, 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?
