How many GFCI circuits does the tub need? Count the labeled cords on your tub, because every one of them needs its own dedicated 20 amp, 120 volt GFCI protected circuit that shares nothing with any other appliance. One line covers hydro only, air only, or hydro plus air. Two lines cover hydro plus microbubble, hydro plus foot massage, and the heated seat variants. Three lines are needed on the ShaK, the Big4One and the two seat tubs with the full package. The first thing to check is the sticker on each cord: on a two line tub they read Line 1 20 Amp and Line 2 20 Amp. A soaking tub with no pumps needs no outlet at all, because the drains are gravity driven.
Likely Causes
- Not knowing the package. The line count follows the pumps and options, not the model name.
- Both plugs on one GFCI. Two labeled cords on one circuit trip the breaker as soon as the second pump starts.
- A 15 amp line where 20 amps is specified. It can work on some lighter packages, but 20 is the published standard.
- Doubling up protection. One GFCI, at the breaker or at the receptacle, is sufficient.
What to Check, in Order
- Count the labeled cords on the tub, or read the package sheet packed with it. Each cord equals one dedicated 20 amp GFCI circuit. The model by model table is in electrical requirements by model.
- Match your package to the count. Hydro only, air only or hydro plus air is one line. Add microbubble, independent foot massage or a heated seat and you are at two. ShaK, Big4One and two seat full packages are three.
- Choose where the GFCI sits. Your electrician can put it at the breaker or at the receptacle; one or the other is sufficient. Keep other appliances at least 3 feet from the tub. See common electrical questions.
- Place the outlets under the seat area, inside or directly behind the equipment compartment, so the pump and heater cords reach without extensions. See outlet placement and cord reach.
- Check the plug type. Some master control boxes carry a 20 amp plug with one blade turned sideways, which needs a 20 amp receptacle. Which cord plugs where is in cords, control boxes and connections after install.
- Ask for the diagram. The team can email the electrical diagram for your model so your electrician has the count and outlet location before rough in.
The video explains that the electrical lines are labeled at the factory for easy identification, that dedicated GFCI protected outlets are required, and that the Jetting Packages tab on the Compare Ella Walk-In Tubs page at ellasbubbles.com lists how many plugs and lines each tub needs.
When to Open a Ticket
If you want the exact count confirmed before your electrician runs wire, open a ticket at ellasbubbles.com/support with your model, the therapies and options on your order, and a photo of the cord labels if the tub has arrived. Your Ella dealer or the team at (800) 480-6850 can send the electrical diagram for your configuration.
