Hello,
I have few questions but will start with this.
I have 200Amp service in my home. I'm building a 28' x 42' workshop that is 150' away and was planning to have a 100Amp subpanel there to feed a variety of items:
- Power Tools
- Lights
- Mini Split AC
- Some 240V machines (Tablesaw, jointer, planer) will run only 1 at a time
While I have a lot of tools, I'm only running one at a time plus a dust collector (probably also 240V).
I was advised to run #3 THHN plus a #8 for ground to the new building. 100 Main Lug panels don't have many spaces (i like Square D so I plan on using a Load Center Convertable Main (Lugs) type....is that still ok? It has 24 slots and is rated for 125A.
Other question - since the building is 150' away, is #3 THHN still ok for 100amps? In the back of my head I wonder if it's more prudent to run #2....also leaves capacity if need to up to 125A down the road (just in case...I worry about these things )
I'm in NJ if matters.
Thanks so much!!
(In addition, I'm aware of need to have 2 ground rods and ensure a ground bar is added to separate from the neutral)
