Yes you could add a double 30 breaker and additional circuits for tools lights or whatever. It should also say how many amps it will pull. But you will need to check the motor on the compressor to see if it requires 240v or 120V. If it runs on 240V then yes you will need a "double pole" breaker so that you grab 120V from each phase for a total of 240. Ground rod is best, or tie it to a copper cold water line (old school).Īs for the appropriate breaker for the compressor, that will entirely depend on the compressor.
You may also want to add a ground at the new panel.
Two will carry the two phases, one will be a neutral, and the other will be a dedicated ground between the two panels. Flip the main cuffot outside so that you can work on the panel inside without worry.įor a 100' run I'd use service cable. So at least one side of the breaker would be hot. In which case it would be unsafe for you to open because you cannot dissconnect the power at the meter. The one on the outside is likely just a shutoff. Yes, you will want to come off of the panel inside the house.
#60 amp sub panel wire size install#
With that 240v compressor 4 each 120v 20 amp circuits would be fine possibly more in a 60 amp panel but I would install a larger panel just in case of future needs. At 100' usually the the wire size won't be needed to be upsized for compressors and welders because they are not continuous loads. The only way to know for sure is to check the mfg install instructions. For example I have an 7 or 8 horse compressor that only requires a 30 amp breaker on 10awg wire but a true 5 horse compressor that draws more. Not FLA + for disconnect and wire size.(note your 16.5 amp size would work on a 20 amp circuit but the mfg instructions need to be followed). Compressor motors may not have "true power ratings" they use locked rotor current. For the breaker size on the compressor get the specs off the compressor. Larger panels are not much more and I have never been asked to down size a panel but have upsized many over the years. As far as the garage panel size I would go bigger, put at least a 100/125 amp panel in this way if later you need more power you only need to upsize the breaker in the house feeding the garrage and the wire gauge. You can run the sub for the barrage to the house sub panel.
#60 amp sub panel wire size plus#
Am I correct that I will need 2 hots, a neutral and a ground running to my sub panel? At just under 100 feet, will 6 awg suffice for a 60 amp sub panel? Then the question becomes, what circuits will I be able to run out of that sub panel? My compressor, plus what? I've learned that I can have four 6 awg wires in my 3/4" conduit.
I also use a welder very intermittently that "works" on a 20a circuit.Īs I continue to browse on this subject. In response to question - Total distance from indoor panel to garage panel is about 100 feet.Īnd, the plate on the motor says 230 volts - 16.5 amps. How many wires of what awg would I need to run from the house panel to the garage in each case? The compressor would need a "dual 30A" breaker - correct? Can I still have another circuit in that panel for a 20A outlet and or a lighting circuit? Or would that require a larger sub-panel? I'm thinking I'd do a 60 amp panel in the garage. I was told to think of the outside box as the "main" panel and the one in the house as a "sub-panel." So, I am essentially running a sub panel from a sub panel. I have a 200 amp shut-off panel on the outside of my house which runs to a 200 amp breaker panel in the house. I would like to run a sub panel out to my garage to run an 80 gal (4hp) compressor.
