What's different about smoke & co detector installation in Trenton
Battery-only smoke alarms must generally be the sealed ten-year type. Renovations under permit typically require hardwired, interconnected alarms. Permits come from the city's construction office under the Uniform Construction Code.
Older rowhomes often have small services, knob-and-tube and patched wiring, and renovations commonly require full rewiring. Basements near the river can take on water.
Weather and the utility in Trenton
Trenton sits on the Delaware River, which flooded the city in 2004, 2005 and 2006, and heavy rain still threatens low-lying neighborhoods and basements. Summers are hot and humid, with thunderstorms that cause outages and surges, and winters bring snow and ice. Older rowhomes often have meters and panels in basements, which makes flooding a direct electrical concern. PSE&G serves Trenton and handles meters, service drops and reconnection.
