Hot Tub Panel
Electrical Question: I want to add a panel for a hot tub, some outlets and lights. Should I run a 100A service panel so I can supply power for all these circuits?
- I have a two story home that has an unfinished basement.
- There is a 200A service in the basement. I also have a semi-detached garage with a 60A panel (no main breaker).
- There is an open porch on the rear of the house that is covered by an existing roof which was part of the original construction.
- I am enclosing this porch and want to wire it with outlets.
- I want to add a hot tub (50A) outside this porch & there is an existing pool pump outside.
- Should I run a 100A service panel on the porch so I can supply the outlets, lights, etc and the hot tub?
- The hot tub will have a disconnect on the outside wall of the porch.
- My 200A panel only has two slots left which is why I want the 100A panel and it makes sense to put the 100A panel on the porch only because of the hot tub and pool.
- Do I need a permit if I do it myself. I don’t mind the fee but the inspectors in our county are kinda tough when they see its a home owner doing the work. Thanks

Thanks for your electrical wiring question Eric.
Installing a Panel for a Hot Tub
Application: Adding a Sub Panel for a Hot Tub.
Skill Level: Intermediate to Advanced. This electrical project is best performed by a Licensed Electrician.
Tools Required: Electricians pouch of hand tools and the various power tools necessary for installing the sub-panel.
Estimated Time: Depends on the type and size of the panel and available access to the project area.
Precaution: Any existing electrical wiring within the immediate area that may interfere with the installation of the sub panel should be identified and turned OFF and Tagged if necessary. Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock.
Notice: Installing electrical wiring for either a hot tub or a sub-panel must be done according to local and national electrical codes with a permit and the work will require inspections.
Project Considerations for a Hot Tub Panel
Panel for a Hot Tub and other Electrical Circuits
- Hot Tub Disconnect
A disconnect is required in the location of the hot tub, no closer than 6 to 10 feet from the inside wall of the tub, and a clearly labeled circuit breaker in a panel may serve as this disconnect.
- Hot Tub Panel
Careful consideration should be given about installing a panel on a porch as there may be clearance and access limitations that may affect working clearance. Installing conduits for electrical wiring of any circuits, as well as the feeder circuit to the proposed panel may be an issue. A panel which supplies power to circuits for an unfinished basement may be best installed inside the basement area in an approved location.
- Project Recommendations
For best results, an on site review of the entire project by a professional who is familiar with the applicable codes would be best. This could include a courtesy visit from one of your local building department representatives, or an electrical contractor who could review the project and make a specific proposal for you.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
