Residential Electrical Wiring

Project: Waterfront Warehouse Rehab, Episode 5, Part 1



Rough electrical work is underway and Bob discusses the challenges of wiring an old building, particularly in New York City where there are strict code requirements.

The electrician, Eddie Fisher, uses metal-shielded cable to reduce the possibility of damaging power lines, both during installation and over the building's lifespan.

Insulation is also going on. Bob joins George Saylor from Owens Corning to learn more about the type of insulation being used in the apartments.

Taking a break from the action at the project building, Bob tours the Brooklyn Navy Yard, the country's oldest dry dock. Now converted for a variety of functions, the Navy Yard houses everything from television and film production studios to commuter boat docks.
Part 1: Residential Electrical Wiring
Bob meets Eddie Fisher, the master electrician on the Brooklyn project's infrastructure team. A team of five electricians from AC/DC Electric is rewiring the building from basement to roof deck. New York City building codes often require the use of materials and techniques not usually seen in residential construction. For example, between the main electrical box and each GFI (Ground Fault Interrupt) circuit, there must be separate power lines. Also required by code is the use of metal-shielded cable (known as BX cable). BX is a rigid, flexible metal conduit with a wire bundle, consisting of individually insulated conductors covered by a flexible spiral-wound layer of metal. BX typically lasts longer than vinyl-clad cable.
