What are the GFCI outlet requirements for NB kitchens?

All kitchen countertop receptacles within 1.5 metres of a sink must have GFCI (Ground Fault Circuit Interrupter) protection under the NB Building Code, which adopts the Canadian Electrical Code. In practice, most electricians in New Brunswick install GFCI protection on all kitchen countertop circuits because it is safer, simpler, and meets code regardless of the exact sink distance.

A GFCI device monitors the electrical current flowing through a circuit and trips within milliseconds if it detects a ground fault — which is what happens when electricity finds an unintended path, such as through water or a person. Kitchens are high-risk areas for ground faults because water, wet hands, and electrical appliances are in constant proximity. GFCI protection has prevented countless electrocutions since it became a code requirement, and it is non-negotiable in any kitchen renovation that involves electrical work.

The NB Building Code also requires a minimum of two dedicated 20-amp small appliance circuits serving kitchen countertop outlets. These circuits must not serve any other loads — no lights, no refrigerator, no dishwasher. Each of these two circuits should have GFCI protection. The outlets must be spaced so that no point along the countertop is more than 900mm (about 3 feet) from a receptacle, ensuring you always have a nearby outlet for countertop appliances without stretching cords across the workspace.

In addition to the countertop circuits, dedicated circuits are required for the refrigerator, dishwasher, range or oven, microwave, and garburator. The dishwasher receptacle should also have GFCI protection given its proximity to water. The refrigerator circuit is sometimes debated — some electricians install GFCI protection on it, while others avoid it because a nuisance trip on a GFCI can shut off your refrigerator while you are away, potentially spoiling food. Discuss this with your electrician to decide the best approach for your situation.

Older NB Homes and GFCI Upgrades

Many New Brunswick homes built before the mid-1980s have no GFCI protection in the kitchen at all. If your home was built in the 1960s, 1970s, or even 1980s, there is a good chance your kitchen has ungrounded two-prong outlets or grounded outlets without GFCI protection on a single 15-amp circuit shared with other rooms. This does not meet current code and is a genuine safety hazard.

During a kitchen renovation, your electrician will bring the electrical system up to current NB Building Code standards for the work being done. This typically means installing GFCI-protected 20-amp circuits for the countertop, adding dedicated circuits for appliances, and potentially upgrading the electrical panel if it is a 60-amp service that cannot support the additional circuits. Panel upgrades from 60-amp to 100 or 200-amp cost $1,500 to $4,000 and are commonly needed in older homes across Moncton, Fredericton, Saint John, and throughout the province.

GFCI protection can be provided either at the receptacle itself (GFCI outlet with test and reset buttons) or at the circuit breaker in the panel (GFCI breaker). Both methods are code-compliant. GFCI breakers protect the entire circuit from the panel, while GFCI receptacles protect downstream outlets from that point. Your electrician will recommend the best approach based on your panel type and circuit layout. Any electrical changes require a permit and inspection — this is not a DIY project, and the permit fees of $75 to $150 are a small price for verified safety.
