A grooming van that powers the dryer without tripping.
The force dryer breaks everything — high amps for minutes at a time, tripping a 15A circuit on high. Tell Wattonomy your kit and it sizes around the dryer and heater, puts the big draws on their own circuits, and draws the wiring.
Wire & fuse sizes follow ABYC E-11 — each conductor carries its fuse and stays under a 3% voltage drop.

Your force dryer trips the breaker — every time.
A high-velocity dryer draws sustained high current, and running it alongside a heater on one circuit is exactly what trips the breaker (or stalls a generator). Wattonomy sizes the system for that sustained load, puts the dryer and heater each on their own dedicated 20A circuit, and sizes every cable to carry its fuse — to ABYC E-11.
What a grooming van has to get right.
It’s the sustained amps, not a momentary surge, that decide this build.
Appointment-day energy
Dryer time across the dogs, water heating per bath, clippers, pump and lights — summed as real Wh for your day.
Sustained-load sizing
The inverter and bank are sized to run the dryer for real, not for a one-second peak — so it holds at full power.
Dedicated circuits
Dryer and heater each on their own 20A circuit — never shared — which is what stops the trips.
Cables & fuses
Every gauge, fuse and AIC matched to the load and your run lengths, to ABYC E-11.

Questions
Why does my dog dryer keep tripping the breaker?
High-velocity dryers pull sustained high amps — often more than a 15A circuit allows on high, and far more when sharing a circuit with a heater. The tool sizes for that sustained draw and puts the dryer on its own 20A circuit so it stops tripping.
Can I run a grooming van on battery instead of a generator?
The core — dryer, heater, clippers, water — can run on a properly sized battery + inverter, silently (which calmer for the dogs). Run a dryer, a tankless heater and a vacuum all at once and you cross into a 240V split-phase build; the tool flags that line and points you to an electrician.
Electric or propane water heating?
A small electric mini-tank fits a 120V build; a true tankless heater at bath flow is a 240V item. The tool sizes the electrical load honestly and tells you which side of the line you’re on.
Do I need an account?
No. Design the whole system free, no email required. Accounts are only for saving builds or the printable build binder.
Is this just trying to sell me a kit?
No. The parts list is vendor-neutral and standards-referenced — buy the components anywhere. We make the design, not the markup.
The standards we build to
Plain version: these are the recognized rulebooks your design is sized against, so the numbers hold up to a surveyor, an inspector or an insurer.
ABYC E-11The US standard for AC & DC wiring on boats — what a surveyor or insurer actually checks.
Wattonomy applies these standards in its calculations. It is not certified, sponsored or endorsed by ABYC, ISO, NFPA or Victron — it sizes your design to meet what they require, and shows the working.
