Help Needed for Electrial Connection

Simple. Get the supply upgraded to 3-phase, of a size suitable for the loads to be expected when the bakery is running full tilt. A telephone call to the utility company is the first step. Get someone round to have a look at it, and discuss the issue with that individual.

You did not register so we don't know where you are. If you are in the US, if you have 110V you have 220V, even if nobody made it available to you in a wall outlet. You need to call an electrician.

If you are not in the US, I have no idea. But calling the utility or an electrician is a good place to start anywhere.

Dear Guest, If you call your utility company they will be happy to tell you if your building is capable of handling your loads ... Since each month you give them a check $$ is that correct? They may say that as a bare minimum is a 208V /120 service in the USA (NEC) as appropriate. Hope this helps, Ray

For up to ~ 3HP motors you can find variable frequency drives (Google VFD) that convert 220VAC 1-phase to 3-phase at very reasonable prices.

At a minimum you will need an electrician to wire 220VAC 1-phase from your existing panel to the new equipment. A VFD will then convert the 1-phase to the 3-phases required by your motors.

Since this will be a commercial site, it may be a better choice to have the utility and an electrician supply the 3-phase power directly. Depending on the building size and location, this may require a significant service and panel upgrade. Many commercial/industrial motors and appliances require 3-phase power so upgrading to 3-phase now may be a good investment.

Best wishes for your Bakery business.
