Hot tub wiring in Redwood Meadows: a 50 amp spa circuit, done to code
July 2026 · Residential · Hot tub wiring · Redwood Meadows, west of Calgary
Koop Electrical wired a new hot tub at a home in Redwood Meadows, west of Calgary, in 2026: a dedicated 50 amp circuit from the panel, a GFCI spa disconnect on the house wall within sight of the tub, and conduit run along the house and across the patio to the tub under its gazebo. Ryan did the job in one day, and the installation passed inspection.
At a glance
Client: A homeowner in Redwood Meadows
Job type: Hot tub wiring — dedicated 50 amp spa circuit
Date: July 2026
Scope: 50 amp two-pole circuit from the main panel; 50 amp GFCI spa disconnect (a "Spa Buddy" pack) mounted on the exterior wall in sight of the tub; conduit along the house and across the concrete patio; final connection to the tub's control pack; GFCI test and inspection
Cost: Koop's hot tub circuits run $1000 to $2,000 depending on the run
Electrician: Ryan
The setup
The tub sits under a cedar gazebo on a concrete patio at the back of the house, about 20 metres from the panel in the basement. The owners wanted the wiring out of sight, the disconnect where the code puts it, and no trench through the yard.
What the code asks for
A hot tub is one of the few things in a house that combines water, bare skin and 240 volts, so the Canadian Electrical Code is specific about it. The tub gets its own circuit, sized to the manufacturer's rating (50 amps for this one). The circuit is GFCI-protected, so a fault trips the power in a fraction of a second. A disconnect has to be within sight of the tub but not right beside it, so someone can cut the power without reaching over the water. Nothing electrical hangs over the tub, and the metal parts around it are bonded. The City of Calgary's own hot tub page says the same things in plainer words.
What we did
Ran a 50 amp circuit from the main panel to the back of the house.
Mounted the GFCI spa disconnect on the exterior wall, in sight of the tub and outside the reach zone.
Ran the conduit along the wall and across the patio to the gazebo, clipped tight to the siding so it disappears against the house.
Connected the tub's control pack and tested the GFCI.
The result
A tub that is safe to use, wiring you have to look for to see, and an owner who wrote: "Ryan from Koop Electrical did a phenomenal job, clean, fast and very good to work with. Would highly recommend."
