At that distance, you are fine with 4/0 4/0 2/0 4 underground MHF

If you can't run a dedicated circuit from your existing main panel, upgrade your panel or service as necessary.

Unless you need more fixtures your best (easiest) option is change the old bulbs to ballest bypass led

De-rate from the 90 degree column

I've seen installations that didn't meet as stringent of a requirement when the AHJ itself was doing the installing.

Does the city own both the park and the utility providing the service?

I put in a 240 volt floor outlet for my table saw when I built my shop building in 1983. Never had any problems with sawdust and I don't drink Pepsi.

OP if you have already run your romex, you asked your question too late. As already pointed out, absolutely not code compliant on new construction to go the afci receptacle route unless you are going conduit system to first metal box, compatiable breaker to receptacle, etc etc. If you are being...

The panel you linked in post #63 has the plug-on-neutral feature. This means you don't need to use the breaker with the pigtail wire. Much cleaner and saves space. Don't know why you would use any arc-fault breakers in a barn or out-building however

Yes you need the four wire feed. Yes the barn needs 2 ground rods or ufer ground (if one was installed prior to foundation pour). Neutral is not bonded to panel box but kept separated from ground. You will need to purchase the ground bar separately for the panel if it is not included. Yes square...

OP you need to find out what code year cycle you are under first, as it could make a big difference in your requirements.

maybe strain relief grommet?

There you go, unless you're not going to wire the building at all

[/GD] I would like to do aluminum and save some $$$ but hearing that the wire can expand and retract over time and cause a fire kind of scares me a bit. Properly installed aluminum feeder cable is perfectly safe
