Hot tub disconnect failed inspection at 86 inches: what the Canadian and US codes require

The electrician laid out the problem on Reddit's r/electricians on Oct. 31. The inspector cited Canadian Electrical Code rule 68-068 6C, which he summarized as 3 meters or a barrier. Moving the box would mean cutting into the patio, and he wrote that no 60-amp GFCI breaker is available for his Square D Homeline panel, so the protection can't simply move indoors.

Ontario's Electrical Safety Authority explained how rules 68-068 and 68-072 work in a 2023 contractor bulletin. The disconnect for an outdoor tub goes outside, and it must be lockable if it isn't within sight of the tub. It has to stay at least 1.5 m away unless a permanent barrier keeps a bather from reaching it. Inside 3 m, it needs GFCI protection from a device that is itself at least 3 m from the tub. Kato Electrical, a Vancouver contractor, describes the same 1.5 m and 3 m bands under the BC code and says a misplaced disconnect sinks more of its hot tub jobs at first inspection than anything else.

The US rule is simpler. The NEC's maintenance disconnect rule, section 680.13 in current editions, calls for a disconnect that is readily accessible, in sight of the equipment and no less than 5 feet from the inside wall of the tub, measured along the shortest path to the switch, unless a permanent barrier stretches that reach to 5 feet, Mike Holt explained in EC&M. Within sight means visible and no more than 50 feet away. The emergency shutoff in 680.41 does not apply to single-family homes. At 86 inches, the box clears the US minimum by 26 inches.

That leaves the Canadian job two ways out without cutting the patio. One is a plain disconnect where the box is now, with the GFCI moved to a device at least 3 m from the water: a breaker in a panel that takes one, or a separate GFCI enclosure mounted farther out. The other is a permanent barrier between the tub and the box that keeps a bather from touching it.
