I am at a limit with my panel for 220v circuits. Can I build a controller from 120v input that will control both march pump & 1500-2000w element for RIMS tube? I don't think you can have more than one receptacle on a 220v line line you can 120v can you? Otherwise my problem is solved.

You should have a question of ampacity. How many amps does your source support? How much additional amperage do you need to drive your secondary controller?

I am not aware of any restriction on adding a second receptacle on a 220V line. All wiring needs to be sized to the amperage of the breaker.

Keep in mind that 'code' states to NOT exceed 80% of the breaker rating.

So can you run a 2000w element (120v) & a marc pump from a control box build & do you have a good build diagram?

It depends on what devices you are using. Even then most of the manuals will show you typical wiring configurations.

Send over a model number for your controller and I can link you to the manual or help you design wiring!

And just to be clear, is your supply voltage 220Vac(3 wire)? Or 120Vac(2Wire)?

120 v 2 wire w/ground. Is this possible? I know just enough about circuitry to be dangerous!

Its a REX-C100 controller. Looks like an Auber but its a Honk Kong spin-off.

Yea it's a question of amperage. But I'd assume that you could, I run 4 elements (7.4kW total) on a 50amps, so that could most likely do both the burner and the pump, maybe even so if your on a 30A.
