Default What to ask an electrcian for?

Hey All,

I am having an electrician out to add a 240 line for a ductless mini split hvac system. I wanted to ask him to run a second "plug" "line" for the future possibility of moving to electric. What do I want to ask them for. I would think i would run an electric brewery with 2x 5500w elements 1 in the HLT the other in the boil keetle with a herms coil and pumps.

From what I understand the 240v line I need for the hvac only requires a 15 amp breaker. I have 3 open slots on my beaker box.

With that, what do I need to ask an electrician to do?

You'll want a 50 amp GFCI breaker installed in the box and then you'll want him to run the line to a 4-prong outlet wherever you want it at. The 50 amp GFCI breaker may be more expensive than having him install a Spa panel.

So basically whatever is better in your electricians opinion. What you will need is 50 amps that is GFCI protected at your outlet.

You probably would want a 50 amp outlet. You could then run 2 4500w elements at the same time. Or if you only plan on using one element at a time you can get a 30amp.

240 volt breakers take 2 slots so you need 4 empty slots to have 2 240 breakers

Could you do your ebrewery near to where the hvac system is being powered?

If so you could ask him to set a subpanel, use a larger breaker in your main eg 80a or 100a, and have 2 separate lines out of the subpanel, 1 x 15a for your hvac and 1 x 50A for brewing

Though if your panel is full (save for 3spots) you might want to do a load calculation to see what kind of overhead you have available

The hvac system and ebrewery could easily be on opposite sides of the same wall. Hvac on the outside ebrewery in the garage.

sounds like its a definite possibility then, if your unsure how to do this yourself theres a load calc available for estimating residential loads on mikeholt.com

You could also have him wire in only one supply to that area, and provide some form of transfer switch inside. Then you'd use the same breaker (50a) in the panel, and with the switch you'd control whether the power goes to your HVAC unit or your outlet for the brewery. You wouldn't be able to run both at the same time, but it would cut down on total equipment and wiring, and reduce your potential total load at the main.

Edit - I just saw you're in Phoenix. No AC for a few hours could be death.

hey everyone,

I finally got the electrician in to add the extra circuit. I hope I did this right. Here is a fuzzy picture of the panel. It's a 240v 30amp circuit. My plan is to run 5500w for the boil kettle and there is a 120v GFCI outlet on the same wall I can run a smaller 1500w element on for the HLT.
