I believe I have a 200A electric service at my house.
If I want to add a 240V outlet in the garage (to power a high power electric pressure washer, or other tools), do I have to upgrade the panel or the service contract with the electric company? The machine draws 20 to 30A.
I'd hire an electrician to add the outlet but I want to know the code related issues beforehand.
It may be cheaper to buy a gas pressure washer but I don't like maintening gas engines. And regular 120V pressure washers are too weak.
