Bob meets Barry Driscoll, the electrician who is wiring a third-floor sub panel. The panel feeds air handlers, bedrooms, bathrooms and an entertainment area. At the time the house was built in 1892, gas, not electricity, was used for lighting. It wasn't until the 1920s that electricity was used in the house. City of Cambridge electrical inspector looks at the sub panel for adequate size and proper location.

Bob joins electrician Jose Rodriguez as he installs wiring in metal framing at the storm-ready house. Rodriguez uses plastic boxes with plastic flanges to house the wiring. Rodriguez also attaches a protective nail plate over the wiring where it crosses the furring strips. The wires are then tied to the studs and run down to the box where they are connected.

In this segment Bob meets Eddie Fisher, the master electrician on the Brooklyn project's infrastructure team. The team of five electricians from AC/DC Electric is rewiring the building from basement to roof deck. Fisher's team is pre-wiring the building for telephones, computer and cable TV. New York City building codes often require the use of materials and techniques not often seen in residential construction. Codes enacted in the summer of 2003 in New York City require a separate power line from the main electrical box to each GFI (Ground Fault Interrupt) circuit. Also required by code in this building is the use of BX, or metal-shielded, 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 will typically last longer than vinyl-clad cable and may prevent some inadvertent damage in the future.
