Can you add both an EV charger and a hot tub to the same electrical panel? Sometimes, but not always, and a load calculation is the only way to know. At a home we recently wired in Milwaukie, Oregon, the new ChargePoint EV charger and hot tub each needed a 50-amp circuit, about 100 amps of new load in all. The home's 125-amp panel couldn't handle that, so we replaced it with a new 200-amp panel. Some homes have capacity to spare, and others can get by with a load management device. Either way, a hot tub needs its own dedicated circuit with GFCI protection and a disconnect within sight of the tub, and the work needs an electrical permit.
Here's how that project went, what we checked, and what homeowners in Milwaukie, Oak Grove, Clackamas, and nearby should know before taking on the same thing.
What did the homeowners need?
The homeowners had bought a hot tub and were adding a ChargePoint Level 2 EV charger, and they wanted both running safely without tripping breakers or overloading their electrical system. The problem was their existing 125-amp panel. It was already serving the rest of the house, and it didn't have the capacity for two big new 240-volt loads.
Can one panel handle an EV charger and a hot tub?
This is the question we get most often from homeowners adding both, and the honest answer is that it depends on the house.
A Level 2 EV charger and a typical hardwired hot tub each need their own 240-volt circuit, and both can draw a lot of power for hours at a time. An EV charges for hours, usually overnight. A hot tub's heater cycles on and off all day to hold the water temperature, and it often runs on cold nights when your furnace or heat pump is working hard too. Under the electrical code, EV charging counts as a continuous load, which means the circuit has to be sized with extra headroom.
To find out whether your panel can take both, a licensed electrician does a load calculation. That's a code-based estimate of your home's demand, adding up your existing appliances, heating and cooling, and the new loads, then comparing the total to your service size. It usually leads to one of three outcomes:
There's enough capacity, and the two new circuits go into your existing panel.
There's capacity, but not much. A load management device or smart panel can limit or pause EV charging when the house is using a lot of power, so you may be able to avoid an upgrade.
There isn't enough capacity. A panel or service upgrade gives you room for both, plus future additions like a heat pump or induction range.
If you want more background on panel capacity and EV chargers, our post Do I Need a Panel Upgrade Before Installing an EV Charger? goes deeper.
What did we do at this Milwaukie home?
This home landed in the third category. The ChargePoint charger and the hot tub each needed a 50-amp breaker, about 100 amps of new load between them, and the existing 125-amp panel didn't have room for that. We replaced it with a new 200-amp panel, which gave the house capacity for both new circuits, with headroom left for future additions like a heat pump or an induction range.
Here's what the job included:
Replacing the 125-amp panel with a new 200-amp panel
A 50-amp circuit for the ChargePoint Level 2 charger, mounted right next to the new panel, which kept that run short and simple
A 50-amp circuit for the hot tub, which sits about 60 feet from the panel
The electrical permit and inspection
Our two-person crew completed the whole project in one day.
A 200-amp upgrade happens to be one of the requirements for PGE's Electrical Service Upgrade Rebate, which can apply when a panel upgrade is needed to add a Level 2 charger. If you're a PGE customer, our post on PGE's panel upgrade rebate for EV chargers explains the rules. You need to check and confirm your own eligibility directly with PGE. Nexus Electrical Group does not apply for, process, or guarantee rebates.
What electrical work does a hot tub need?
The National Electrical Code (NEC) covers hot tubs and spas in Article 680, and Oregon's electrical code is based on the NEC. The specifics depend on the tub and the manufacturer's instructions, but most hardwired hot tubs need:
A dedicated 240-volt circuit sized to the tub's nameplate rating. The tub in this project needed a 50-amp breaker, but it varies by model, so always go by your tub's specs.
GFCI protection. Water and electricity don't mix, and the code requires ground-fault protection for hot tub circuits. This is often built into the outdoor disconnect.
A disconnect within sight of the tub. It has to be easy to reach and at least 5 feet from the inside wall of the tub, unless a permanent barrier separates them, so you or a service tech can safely shut off power.
Proper bonding and grounding of the tub's metal parts and nearby equipment, which reduces shock risk.
Wiring rated for the conditions, especially when the tub sits out in the yard, like the one in this project about 60 feet from the panel.
Plug-in "plug and play" tubs that run on 120 volts are a different setup. They still need a properly protected outlet, and the manufacturer's instructions usually spell out the requirements.

Do I need a permit in Milwaukie or Clackamas County?
Yes. Oregon requires an electrical permit before this kind of work starts, and who issues it depends on where you live:
Inside Milwaukie city limits, the City of Milwaukie Building Division issues electrical permits. The city says it contracts with Clackamas County for electrical plan reviews and inspections, so a county inspector may be the one who comes out.
In unincorporated areas such as Oak Grove and Clackamas, Clackamas County Building Codes issues the permits.
In other cities like Gladstone or Happy Valley, whether the city or the county handles electrical permits varies by city. Clackamas County keeps a jurisdiction lookup.
As a licensed contractor (CCB #226988), we pull the permit and schedule the inspection as part of the job. The inspection is your independent check that the work meets code.
What did the homeowners think?
They were happy with how it turned out, and they left us a 5-star review on Google. Their EV charger and hot tub both run on the new 200-amp panel, with room to spare for whatever they add next.
What does this cost?
Every home is different. Panel capacity, the distance from the panel to the charger and the tub, and whether an upgrade is needed all change the price. Rather than repeat it here, our 2026 cost guide for EV chargers and panel upgrades walks through what drives the numbers.
If you're a PGE customer, there may be utility rebates for a Level 2 charger and a related panel upgrade (see the PGE rebate post). You'll need to confirm your eligibility directly with your utility. Nexus Electrical Group does not apply for, process, or guarantee rebates.
Frequently asked questions
Can I put an EV charger and a hot tub on the same electrical panel?
Sometimes. It depends on whether a load calculation shows the panel and service have enough capacity. If they don't, the options are a panel or service upgrade, or a load management device that limits EV charging when the house is using a lot of power. At one Milwaukie home, the two added about 100 amps of load, and we upgraded a 125-amp panel to 200 amps.
Does a hot tub need its own circuit?
Hardwired hot tubs need a dedicated 240-volt circuit with GFCI protection, sized to the tub's nameplate rating, plus a disconnect within sight of the tub. The tub in our Milwaukie project needed a 50-amp breaker.
How far does a hot tub disconnect have to be from the tub?
The NEC generally requires the disconnect to be within sight of the tub and at least 5 feet from its inside wall, unless a permanent barrier separates them. Your electrician and inspector will confirm the right location for your yard.
Will I need a panel upgrade to add an EV charger and a hot tub?
Not always, but it's common in homes with smaller panels. At the Milwaukie home in this post, the EV charger and hot tub each needed a 50-amp breaker, and the 125-amp panel had to be upgraded to 200 amps. Homes that already have 200-amp service often have room. A load calculation is the only way to know.
How long does a panel upgrade with an EV charger and hot tub circuit take?
It depends on the home and the permit and inspection schedule. On this Milwaukie project, our two-person crew finished the panel upgrade, the EV charger, and the hot tub circuit in one day.
Who issues electrical permits in Milwaukie, Oregon?
Inside Milwaukie city limits, the City of Milwaukie Building Division issues electrical permits, and the city contracts with Clackamas County for electrical plan review and inspections. In unincorporated areas like Oak Grove, Clackamas County issues them.
Do you work in Milwaukie, Oak Grove, Gladstone, Happy Valley, and Clackamas?
Yes. We're based in Beaverton and serve the Portland metro, including Milwaukie and Clackamas.
Are there rebates for an EV charger or panel upgrade?
PGE customers may qualify for rebates through PGE's Smart Charging program, including a panel upgrade rebate that requires upgrading to 200 amps or more. You need to check and confirm eligibility with your utility yourself. Nexus Electrical Group does not apply for, process, or guarantee rebates.
