I have a 100a main panel that I need to get a 60a subpanel from for garage power, This subpanel is needed for a 220v compressor and (2) curcuits for receptacles. The compressor is currently being ran from a dbl pole 20/20 breaker in the main panel. I would like to remove this 20/20 breaker. install a dbl 60/60 breaker and run it to the garage to a 60a (2-4) space subpanel. Can I use 310.15 and (b) does this look like the best way to do this??? Thanks, JB
 
If you're referring to Table 310.15(B)(6) the answer is no. But removing the 2P/20 and replacing it with a 2P/60 is a good start.

I was referring to table 310.15 (B)(6) for the size of of the wire feeding the subpanel. This is before I went out and got my NEC book....So I should use #6 using table 310.16 for a 60a subpanel? This is going to an attached garage about 35' in the crawl space then up into the garage. Thanks, JB

Yes 310.16 for conductor ampacity. What type of feeder will you be running? Conduit? SE cable? NM cable?

I was going to use conduit to the crawl space then flex to the subpanel? Suggestions?? Thanks. JB

no idea?? could someone have tried to cut out for wrong breaker then someone came along and replaced with the right one later???:-?

Only asking because the wiring method with #6 AWG may affect your OCPD ampacity. THHN within a raceway could be protected up to 70 amps, NM or SE(Cu) up to 60 amps.

I wasn't sure if they made #6 NM..I planned on using THHN, But if I use any of the wire you mention I would still be good to go as far as OCPD Right? Thanks JB

You should correct that double-lugged 2pole breaker in the bottom right space..:)

Those are type CH breakers, which are rated for (2)#14-10 wires on 10-30A 1&2P breakers, so there is no correction needed.
 
Those SPIDER WEBS in the upper right, feed from a 2x30 (?)
Is this for another sub-panel project he has not mentioned ??
Can't quite see where they go!

Up to the Garage???

Watch for your wire to have THHN and dual rated with THWN... : )
Maybe, I don't know...
