I have a nordic track treadmill 3000. They told me, at first, I needed a 20 amp wall outlet.
Now they tell me I need to run a 330v line to the treadmill. Does anyone know if that is necessary? Is there anything else I can do?
Thanks

See If there is a Name Plate with Volts, Amps, Watts, anything?
They might mean 30 amp 240 volts?

Who is "they"??

330v is not a North American nominal voltage. It's either 120, 240, or both.

I HIGHLY doubt a treadmill would require a 30A 240v circuit.

Do as Strat suggests. Post the name plate info.

Your are right! It is 220v.
I only have 110v and 20amp receptacle
Sorry

So what does it say on the name plate?
Amperage and voltage?
