What are the electrical requirements for a kitchen island in New Brunswick?

A kitchen island in New Brunswick requires at least one electrical outlet, and any outlet within 1.5 metres of a sink must have GFCI protection under the NB Building Code. Beyond the code minimum, most modern kitchen islands benefit from two to four outlets, a dedicated circuit for built-in appliances, and consideration for under-counter lighting and pop-up or floor-fed power connections.

The NB Building Code, which follows the Canadian Electrical Code, requires that kitchen islands with a long dimension of 600 mm or greater and a short dimension of 300 mm or greater must have at least one receptacle outlet. This outlet must be supplied by one of the two required 20-amp small appliance branch circuits that serve the kitchen countertop. In practice, most electricians in Moncton, Fredericton, and Saint John recommend installing at least two outlets on a kitchen island, placed on opposite ends, so you have convenient power access regardless of where you are working.

If your island includes a sink, all outlets within 1.5 metres of the sink edge must be GFCI-protected. This is a non-negotiable code requirement. If your island includes a dishwasher, it needs its own dedicated 20-amp circuit separate from the countertop small appliance circuits. A built-in microwave drawer or warming drawer in the island also requires a dedicated circuit. Each dedicated appliance circuit adds $200 to $500 to the electrical budget depending on the distance from your panel.

Getting Power to the Island

The biggest challenge with island electrical is routing the wiring. Since the island sits in the middle of the floor away from walls, power must come from somewhere. The most common approaches are running wire through the floor from the basement or crawlspace below, or running it through the ceiling and down through the wall if the island is against a knee wall or partial wall.

In many older NB homes with unfinished basements, running wire through the floor is straightforward. The electrician drills up through the subfloor into the island cabinet cavity and routes the wire through the floor joists below to the electrical panel. If your kitchen is on a concrete slab, which is less common in NB but found in some split-level homes and additions, the electrician must either cut a channel in the concrete (expensive, $500 to $1,000 for the concrete work alone) or run conduit across the ceiling and down a support post.

For outlet placement, pop-up outlets that sit flush with the countertop when not in use are increasingly popular in NB kitchen renovations. They cost $80 to $200 per unit plus installation and keep the island's appearance clean. Alternatively, outlets can be installed on the side panels of the island below the countertop overhang, which keeps them accessible but less visible.

Budget $500 to $1,500 for island electrical work in a typical NB kitchen renovation, depending on the number of outlets, dedicated circuits, and routing complexity. If your home has a 60-amp electrical panel, common in NB homes built before the 1980s, adding island circuits may push your panel beyond capacity, requiring an upgrade to 100-amp or 200-amp at $1,500 to $4,000. All island electrical work requires a permit and inspection through your local municipality or Regional Service Commission. A licensed electrician should handle this work, as incorrect island wiring is a common inspection failure point.
