Backyard projects tend to arrive with an electrical surprise. Here is what each one needs.
Hot tubs and swim spas
Most full-size tubs need a 240 volt, 50 or 60 amp circuit with GFCI protection and a disconnect within sight of the tub, at least five feet from the water. Metal parts nearby must be bonded. See hot tub electrical installation.
Outdoor outlets
Exterior receptacles need GFCI protection and weatherproof in-use covers. If yours stop working after rain, see GFCI outlet installation. For more of them on the deck or patio, see outlet installation.
Lighting
Low-voltage landscape lighting is safe, efficient and easy to extend. Security floodlights and wall fixtures run on line voltage. See outdoor lighting installation.
Sheds and detached garages
Real power in an outbuilding means a buried feeder and a sub panel. See garage electrical installation.
Is the panel big enough?
A hot tub is a large load. If the panel is already full, the project may start with an electrical panel upgrade. For a fan on the covered porch, see ceiling fan installation.

Quick answers
Can I use an extension cord for a hot tub?
No. Even plug-in models need a dedicated GFCI outlet within reach of their own cord.
How deep is outdoor cable buried?
It depends on the wiring method: commonly 18 inches for conduit and 24 inches for direct-burial cable.
