Outdoor Power: Sized Right, Sealed Against The Weather

Outdoor Power In Vacaville: Capacity First, Then The Trench

Adding power outside the walls of the house is where load math stops being optional. An exterior outlet for a pressure washer is one thing. An EV charger, a spa, or a feed out to a detached garage is current the existing panel may not have to spare. The failure mode that gets people in trouble is the same one every time: somebody runs a new circuit off whatever was nearest without checking whether the panel could carry it, and the result is nuisance trips at best and an overloaded service at worst. Steve Torres has spent thirty years in the tools, much of it in all-weather Navy environments, and on every exterior job the panel gets opened and the numbers get run before a shovel goes in the ground.

GFCI Is The Non-Negotiable Outside

California code requires ground-fault protection on every outdoor receptacle, and there is no version of this work where it gets left off. Exterior outlets get used for tools, pumps, holiday lighting, and pressure washers, all of it run by people standing on wet concrete or damp grass. Ground-fault protection is the difference between a tripped outlet and a shock that finds a path through a person to ground. We install weather-resistant devices in weatherproof boxes, fit in-use covers so the seal holds while a cord is plugged in, and test every receptacle before we close out the job. An exterior outlet without GFCI is not a finished outlet.

Burial Depth Is Set By The Wiring Method

How deep an outdoor circuit has to go is not a fixed number, it depends on what the wire is run in. Direct-burial cable on its own sits deep, because only the soil protects it from the next shovel. The same circuit inside rigid or schedule-40 conduit can run much shallower, because the conduit takes the hit instead of the wire. People who guess either bury too shallow and clip the line planting a tree, or trench far deeper than the code ever required. We follow the depth table for the method we are actually using, sleeve runs in conduit where they cross under a driveway or walk, and seal every below-grade connection so groundwater cannot creep into a splice and corrode it out.

EV Chargers, Spas, And RV Outlets

The high-draw exterior loads are where sizing matters most. An EV charger needs a dedicated circuit with the breaker and wire matched to the unit and the run length, plus a weather-rated receptacle or hardwired disconnect outside. A hot tub or spa is a code-heavy install: a dedicated GFCI circuit, a disconnect within sight of the tub at the required distance, and bonding that ties every piece of metal around the water to the same potential so a fault cannot put a voltage difference across someone in the water. An RV outlet, 30 or 50 amp, gets its own dedicated circuit at the pad. Each of these starts with a load check, because adding any one of them to a panel that is already near capacity is how a service gets overloaded.

Sub-Panels To Detached Structures, Done Right

Feeding a detached garage, shop, shed, or ADU is the job most often done wrong, usually by stretching an extension off an indoor circuit and calling it power. For anything beyond a single light, the correct answer is a properly sized sub-panel at the structure with its own grounding electrode and a feeder sized for the load and the distance. We run the calculation, pick the feeder and the burial method to code, set the sub-panel and its grounding at the building, pull the permit, and coordinate the inspection. The result is a structure with real, safe, expandable power instead of a stretched cord that trips every time two things run at once.
