The breaker tripped on day two. A new spa owner had set up her treatment room with a facial steamer, a towel warmer and a secondhand stand dryer, all plugged into one power strip behind the bed. The steamer alone was fine. The dryer was fine. Together, on one 15-amp circuit, they weren’t — and the room went dark mid-facial, which is the kind of first impression you don’t get back.
Electrical mistakes are the most common problem we see with spa equipment after it reaches the US. It’s not that the machines are bad; it’s that nobody checked the spa equipment power requirements before plugging in. This guide covers the voltage basics, how much wattage each device type draws, and the questions to ask before you order — especially when buying factory-direct.
Voltage: The 110V Question
US homes and salons run on standard 110–120V outlets (15 or 20 amp). Equipment sold for the American market is built for that. The trap is ordering from a factory or marketplace listing that ships the 220V version meant for Europe or Asia — it won’t run on your outlet without a heavy step-up transformer, and running a 2,000W dryer through one is asking for trouble.
Two things protect you. First, buy dual-voltage (110–240V) equipment when you can, so the same unit works in the US now and anywhere later. Most of Nova’s electric equipment ships dual-voltage with CE certification and a US-standard plug — just confirm your order is set for 110V before it leaves the factory. Second, always check the nameplate sticker on the unit for voltage and wattage before you plug anything in. If a deal looks too good, ask which voltage it actually is.
How Much Power Each Device Draws
| Equipment | Typical Wattage | Outlet / Circuit Note |
|---|---|---|
| UV/LED nail lamp | 40–120W | Any standard outlet |
| Wax warmer | 100–300W | Any standard outlet |
| Towel warmer | 200–600W | Any standard outlet |
| Facial steamer / mist machine | 250–700W | Fine on a shared outlet with low-draw items |
| Console / floor hair steamer | 800–1,500W | Best on its own circuit |
| Hooded or wall-mounted hair dryer | 1,000–1,900W | Dedicated circuit recommended |
| Stand dryer / processing accelerator | 1,200–2,000W | Dedicated 15 or 20 amp circuit |
The 80% Rule and Shared Circuits
Here’s the math that prevents most breaker trips. A standard 15-amp, 120V circuit can deliver about 1,800W total, and the electrical code says you shouldn’t load it past 80% continuously — about 1,440W. A 20-amp circuit gives you roughly 1,920W of comfortable headroom.
Now think about what runs at the same time in a treatment room: a steamer (say 600W) plus a wax warmer (200W) plus a lamp (100W) is fine. A steamer plus a 1,500W dryer is not. Rules that save you pain:
- Never put two high-wattage appliances (dryers, steamers, towel warmers) on the same circuit.
- Skip power strips for anything over ~1,000W. Plug high-draw machines straight into the wall.
- Use GFCI-protected outlets anywhere near water — backwash stations, shampoo bowls, foot basins. This is code in most states and non-negotiable for insurance. See our shampoo beds for specs and pricing.
- Know which outlets share a breaker. Flip the panel and label your room’s circuits before you wire the equipment, not after.
Plan Outlets Before You Order Equipment
Count the devices per station and give each station two outlets — one for the machine, one for the lamp or charger. Beds and chairs should sit close enough that cords don’t stretch across walkways, and it’s worth paying for floor outlets under treatment beds so nobody trips on a cord mid-service. If you’re leasing, confirm with the landlord how many dedicated circuits the space has; adding a circuit later costs $250–$600 depending on your area, so it’s far cheaper to do during build-out than after the equipment arrives.
What to Ask the Supplier Before You Pay
- “Is this unit 110V only, or dual-voltage 110–240V?”
- “Does it ship with a US-standard plug, and how long is the cord?”
- “What’s the wattage on the nameplate?” — compare it against your circuit plan.
- “What certifications does it carry?” — Nova equipment is CE certified; request the paperwork with your order.
- “What’s the warranty?” — Nova covers equipment for one year, so a faulty unit is replaced rather than repaired by a local tech.
And because most of this gear ships from overseas, remember the timeline: factory-direct orders like Nova’s run 10–15 days of production plus 4–6 weeks of DDP door-to-door ocean shipping to the US, with customs and final delivery included. Order with the electrical plan already done, and the equipment plugs straight in when it lands.
Frequently Asked Questions
Do I need special outlets for spa equipment?
Most small devices — lamps, wax warmers, facial steamers — run fine on standard US outlets. High-wattage dryers and console steamers above roughly 1,200W deserve their own circuit, and anything near water needs a GFCI outlet.
Will a 220V machine work in the US?
Only with a large step-up transformer, which is expensive and inefficient for high-wattage devices. Buy equipment built for 110V, or dual-voltage 110–240V units, instead.
Can I run a steamer and a hair dryer on the same outlet?
Not if they’re both high wattage — a steamer plus a 1,500W dryer can exceed a 15-amp circuit’s capacity and trip the breaker. Put the dryer on its own circuit or run them at different times.
How long does equipment shipping to the US take?
With factory-direct DDP ocean freight, figure 4–6 weeks after the 10–15 day production window. Customs and door delivery are included, so there are no surprise fees at your door.
