How much for an electrical fault investigation in a NB home?

Electrical fault investigations in New Brunswick typically cost $150-$350 for the diagnostic visit, with additional charges for repairs once the problem is identified.

The cost depends on several factors including the complexity of the issue, time required to locate the fault, and whether it's during regular hours or an emergency call. Most licensed electricians in New Brunswick charge a diagnostic fee that covers the time spent troubleshooting, testing circuits, and identifying the root cause of electrical problems.

What's included in a fault investigation:

• Visual inspection of panels, outlets, and visible wiring


• Testing circuits with specialized equipment (multimeters, circuit analyzers)


• Checking for loose connections, damaged wiring, or faulty components


• GFCI/AFCI testing if applicable


• Written report of findings and recommended repairs

Emergency vs. regular service affects pricing significantly. After-hours calls (evenings, weekends, holidays) typically add $50-$100 to the base diagnostic fee. However, electrical faults causing burning smells, sparking, or complete power loss should be treated as emergencies - safety comes before cost.

Common electrical faults in New Brunswick homes include issues with older Federal Pacific or Zinsco panels (fire hazards), knob and tube wiring problems, aluminum wiring connections loosening over time, and moisture-related issues from our maritime climate. Ice storm damage to service entrances is also frequent, requiring both NB Power and electrician involvement.

The diagnostic fee is usually applied toward repair costs if you hire the same electrician. For example, if the investigation reveals a faulty breaker ($200 to replace), you'd pay the total repair cost minus the diagnostic fee. However, if the issue requires extensive rewiring or panel replacement, you'll want multiple quotes since costs can range from hundreds to thousands of dollars.

TSANB permits may be required depending on what repairs are needed. Simple component replacements typically don't need permits, but any new circuits or panel work will require proper permitting and inspection.

For safety reasons, never attempt to investigate electrical faults yourself - even "dead" circuits can be energized through backfeeding or improper wiring. Licensed electricians have the proper testing equipment and training to safely diagnose electrical problems.
