FAQs
Do I need a permit for a whole-house rewire in Townsend?
Yes. Townsend requires an electrical permit for any full or partial rewire. You (or your licensed electrician) must submit an application to the Townsend Building & Inspection Department before work begins. The permit package must include a floor-plan showing new circuit layouts, service size, panel location, and load calculations. Work started without a permit can result in double fees and a stop-work order.
Which electrical code edition does Townsend follow for residential rewires?
Townsend has adopted the 2020 National Electrical Code (NEC) with a handful of local amendments that are published in the town’s Municipal Code, Chapter 5—Buildings. These amendments include stricter AFCI requirements on all habitable room branch circuits, an outdoor service disconnect within 3 ft of the meter, and mandatory tamper-resistant receptacles in all areas. Always cross-check both the NEC and the local amendments when planning your installation.
What service-upgrade rules apply when I rewire an older home?
If your existing service is less than 150 A, Townsend requires it be upgraded to a minimum 200 A during a full rewire (unless a load calculation stamped by a PE proves a smaller service is adequate). The meter base must be ring-type, the service disconnect must be located outside or immediately inside the point of entry, and the grounding electrode system must be brought up to current code (two 5⁄8 in. × 8 ft. ground rods at least 6 ft apart or a concrete-encased electrode). Any overhead service conductors lower than 12 ft above grade at their lowest point must be raised to meet clearance rules.
Where are GFCI and AFCI devices required under Townsend’s local amendments?
GFCI protection is required for receptacles in kitchens, bathrooms, laundry areas, garages, unfinished basements, exterior outlets, and within 6 ft of any sink. Townsend also mandates GFCI protection on dishwasher and disposal circuits. AFCI protection is required on all 120-V, 15- and 20-A branch circuits serving habitable rooms—including kitchens and laundries—whether the wiring method is NM-B, MC, or conduit. Combination AFCI/GFCI breakers are acceptable where both protections are needed on the same circuit.
How must grounding and bonding be handled during a whole-home rewire?
All new branch circuits must include an equipment grounding conductor (EGC). BX or older NM cable without a bonding conductor cannot be re-used. The grounding electrode system must tie to two ground rods or an existing UFER, bond to the metallic water service within 5 ft of entry, and bond any CSST gas piping with a #6 AWG copper conductor. Metal boxes must be bonded via a pigtail or listed clip, and the main bonding jumper in the service equipment must be sized per NEC 250.102(C).
What inspections will the Townsend Building Department perform?
1. Rough-in Inspection: Conducted after all cable, boxes, and bonding are installed but before insulation or drywall. All splices must be visible, and cables supported within 12 in. of each box. 2. Service Inspection: Sometimes done with the rough-in. The inspector checks the meter base, service mast, grounding electrode conductors, and panel labeling. 3. Final Inspection: Performed after devices, fixtures, and breakers are installed and the system is energized. All devices must be labeled, AFCI/GFCI breakers tested, and circuit directory completed. 4. Re-inspection (if needed): Required if any violations are found. Once the final is approved, the Building Department releases a Certificate of Completion, allowing the utility to make the permanent service connection.
