Common Electrical Code Violations in New Brunswick Homes

Whether you're buying a home, renovating, or just want to ensure your home is safe, knowing the most frequently cited electrical code violations helps you identify potential hazards. These are the issues TSANB inspectors and home inspectors find most often in NB homes.

1. Missing GFCI Protection (Most Common)

The CEC requires GFCI-protected receptacles near water sources. The most common locations found without GFCI in NB homes:

• Bathroom outlets — especially in homes built before 1990
• Kitchen outlets within 1.5m of sink — older kitchens often have none
• Outdoor receptacles — frequently overlooked
• Garage receptacles — many NB garages have standard outlets
• Unfinished basement outlets — damp environments without protection

Fix: Replace standard outlets with GFCI receptacles ($15–$25 each) or install GFCI breakers ($40–$80 each). A whole-house GFCI upgrade runs $600–$1,500.

2. Open Junction Boxes / Missing Cover Plates

Every electrical junction (where wires are spliced) must be enclosed in an accessible box with a cover plate. Common violations:

• Junction boxes in attics or basements left without covers
• Wire splices made outside of a box ("flying splices" in walls or ceilings)
• Boxes buried behind drywall during renovations (must remain accessible)
• Missing blank cover plates on unused boxes

Fix: Install cover plates ($0.50–$2 each) on all open boxes. Enclose any exposed splices in proper junction boxes ($5–$15 each plus labour).

3. Overcrowded (Overfilled) Electrical Boxes

The CEC specifies box fill calculations — the maximum number of wires, devices, and clamps allowed in each box size. Violations occur when:

• Too many wires are crammed into a small box (common when circuits are added over the years)
• A smart switch or GFCI outlet (which are physically larger than standard devices) is forced into a shallow box
• Cable clamps are missing and wires enter the box without strain relief

Fix: Replace with a larger box if overcrowded. For renovations, use deep boxes (3.5" depth vs. standard 2.5") to allow adequate space.

4. Improper or Missing Grounding

• Three-prong outlets with no ground wire — the most common violation in homes built before 1970. Someone replaced the original 2-prong outlet with a 3-prong without adding a ground.
• Missing bonding on water pipes, gas pipes, or metal ductwork
• Ground rod missing or disconnected — the connection from your panel to the ground rod outside your home
• Improper grounding of sub-panels — sub-panels must have separate ground and neutral buses, bonded only at the main panel

Fix: Add ground wires, install GFCI protection (code-compliant alternative for ungrounded outlets), or rewire as needed. Ground rod installation: $200–$400.

5. Overfusing / Wrong Breaker Size

Using a breaker or fuse rated higher than the wire gauge allows:

• 20A breaker on 14 AWG wire (should be 15A max)


• 30A fuse on 14 AWG wire in old fuse boxes (extremely dangerous)


• Double-tapped breakers (two wires on a single-pole breaker not rated for it)

Fix: Replace with correctly sized breakers. If the circuit needs more capacity, run new properly sized wiring. Double-tapped breakers need either a tandem breaker or an additional breaker slot.

6. Exposed or Unprotected Wiring

• NMD90 cable run across exposed surfaces without protection (must be protected from physical damage within 1.5m of floor in accessible areas)
• Cable not secured within 300mm of boxes and every 1.2m along runs
• Missing nail plates where cables pass through studs or joists within 32mm of the edge
• Romex used outdoors (NMD90 is for indoor dry locations only — outdoor/underground requires NMWU or conduit)

Fix: Add cable staples, nail plates, and conduit protection where required. Replace improperly used cable types.

7. Improper Bathroom and Kitchen Wiring

• Kitchen counter receptacles not on 20A dedicated circuits (two required by CEC)
• Bathroom outlets sharing a circuit with hallway or bedroom outlets
• Exhaust fan not vented to exterior (vented into attic or soffit instead)
• Light fixtures in shower/tub zone not rated for wet locations

8. Extension Cords as Permanent Wiring

Using extension cords as permanent wiring is a code violation and fire hazard. Common in NB homes:

• Extension cord run through a wall, ceiling, or under a carpet


• Power strip daisy-chained to another power strip


• Extension cord permanently powering a window AC unit or space heater

Fix: Install permanent outlets where needed. A new outlet installation costs $200–$400.

9. Unpermitted Work

Strictly speaking, any electrical work beyond basic maintenance that was done without a TSANB permit is a code violation. Signs of unpermitted work:

• Amateur wiring (inconsistent wire colours, electrical tape instead of wire nuts, exposed copper)


• Circuits not matching the panel directory


• New outlets or fixtures with no record of permits


• Work that doesn't match the home's original vintage (modern devices in unusual locations without proper routing)

10. Smoke and CO Detector Deficiencies

• Missing smoke detectors on required levels
• Smoke detectors past 10-year expiration
• No CO detectors where required (near fuel-burning appliances)
• Detectors not interconnected in new construction or major renovation

What to Do About It

If you suspect your NB home has code violations:

Have a TSANB-licensed electrician do a safety inspection ($200–$400 for a typical home)

Prioritize safety issues — missing GFCIs, overfused circuits, ungrounded outlets, and open junction boxes are the highest-risk items

Fix violations before selling — home inspectors report these to buyers, who either negotiate the price down or demand repairs

Don't panic about older code standards — existing wiring installed to the code in effect at the time of installation is grandfathered. Violations occur when work was done improperly, when modifications didn't meet the code at the time, or when safety equipment is missing.
