Question 1

Romex vs BX cable — which should I use?

Accepted Answer

For most residential applications in New Brunswick, Romex (NMD90) cable is the standard choice, while BX (armored cable) is required in specific situations where physical protection is needed.

The choice between these cables depends on your installation location and New Brunswick's adoption of the Canadian Electrical Code. Romex cable (technically called NMD90 in Canada) consists of insulated conductors wrapped in a plastic sheath. It's less expensive, easier to install, and perfectly suitable

Question 8

What is aluminum wiring and is it safe in my New Brunswick home?

Accepted Answer

Aluminum Wiring in New Brunswick Homes: Safety and Solutions

Aluminum branch circuit wiring was installed in Canadian homes from approximately 1965 to 1976, when copper prices spiked and aluminum became the affordable alternative. Many New Brunswick homes from this era — particularly in suburban developments in Moncton, Fredericton, Saint John, and Riverview — have aluminum wiring.

Question 9

What size wire do I need for different electrical circuits in my home?

Accepted Answer

Wire Gauge Guide for Residential Electrical Circuits in New Brunswick

Using the correct wire gauge (thickness) for each circuit is critical for safety. Undersized wire overheats under load, creating a fire hazard. The Canadian Electrical Code specifies minimum wire sizes based on circuit amperage.

Wire Gauge Basics

Wire gauge in Canada uses AWG (American Wire Gauge) numbers. Lower numbers = thicker wire = more current capacity. The most common residential wire sizes:
