A dedicated GFCI circuit from your panel to the tub, with the shutoff where the inspector wants it. Ready the day the tub is delivered.
Next Phase Electric wires hot tubs and swim spas for homes across South King and Pierce County. A full-size tub needs its own 240-volt circuit, usually 50 amps, protected by a GFCI, with a shutoff you can see from the tub and at least five feet from the water. We check the panel has the capacity, run the circuit in conduit to the pad, connect the tub, and pull the electrical permit. Most jobs take half a day to a day.
Same rules for all of them: dedicated, GFCI-protected, shutoff in sight.
The standard job: a 50- or 60-amp circuit, a GFCI shutoff by the tub, liquid-tight conduit to the control box, tub connected and tested.
These want a dedicated 20-amp GFCI outlet within reach of the cord. Sharing a circuit with the patio lights is why they trip.
The new tub rarely matches the old wiring. We test what is there, reuse what is sound, and replace the breaker, shutoff or wire that is not.
Bigger loads, sometimes two circuits. We size them from the nameplate, not from what the last tub had.
Three rules the inspector checks, and why they exist.
Most 240-volt tubs call for a 50-amp, 4-wire circuit; some need 40 or 60. The nameplate or the manual says which. Nothing else shares it.
Water and 240 volts together is the reason GFCI exists. It cuts the power in a fraction of a second if current leaks. It lives in the shutoff box or in the panel.
Within sight of the tub and no closer than five feet from the water. Close enough to kill the power before servicing it, too far to touch while you are in it.
It changes the electrical job completely.
| 240-volt hardwired | 120-volt plug-in | |
|---|---|---|
| Circuit | Dedicated 50-amp, 4-wire, from the panel. | Dedicated 20-amp GFCI outlet. |
| Heater and jets | Run together, so it holds temperature with the jets on. | Usually one or the other, so it cools while the jets run. |
| Permit | Yes. New circuit, inspected. | Only if a new outlet or circuit is added. |
| Panel capacity | Needs two spaces and real spare capacity. We check first. | Rarely an issue. |
We wire the tub you bought. We are an electrical contractor, not a dealer for any brand.
Licensed, bonded and insured. Background-checked crew.
Send the model of the tub or its electrical spec sheet, and a photo of the panel. A technician reaches out within 1 business hour.
Capacity, breaker spaces, the route to the pad, where the shutoff goes. Exact price before any work, approved by you first.
Circuit in, shutoff mounted, tub connected, GFCI tested. Often done before delivery so the tub fills the day it lands.
Repairs: King and Pierce County south of I-90. Installations: greater Puget Sound.
Yes, and it is the best way. We run the circuit and mount the shutoff ahead of time, leave the last few feet coiled, and come back to connect the tub once it is on the pad. Some people have us do both the same day.
A 200-amp panel usually can. A 100-amp panel with electric cooking and a dryer often cannot take another 50 amps. We run the load calculation and, if it is short, price a subpanel or a panel upgrade alongside.
At least five feet from the edge of the water and within sight of the tub. We also keep outlets and lights at the distances the code sets around the tub.
Yes. It is a new circuit and it gets inspected. Washington L&I issues the electrical permit in most of our area; Burien, Des Moines, Federal Way and Renton issue their own, and Tacoma Power covers Tacoma. We pull the permit and meet the inspector.
A failing heater element is the usual cause, then a pump, then water in a connection. On a plug-in tub it is often a shared circuit. We test each part in turn to find which one is leaking current.
Half a day when the panel is on the same side of the house as the tub. A long run, a trench across the yard or a subpanel makes it a full day.
It depends on the distance from the panel, the amperage and whether the panel has room. You get the exact price after we see it, before any work starts.
Book online or call. Wired and inspected before delivery day.
