I have been considering putting a sub-panel out in my attached garage, wanted to know if I have all my ducks in a row before starting the process and pulling a permit.
Items to be powered - Table saw (15A), Miter saw (15A), Planer (15A), Jointer (15A), Dust collection (240v-4A/120v-8A), All other tools/chargers will be less than 4A.
I figured at any given time that no more than 47amps would be used at any given time. (15*1.25+15+8+5)
Main breaker in the house is 100amp and I plan to leach off from a 60amp double pull breaker to this box (all major appliances that can be are gas)...
I believe this box has a ground bar intended for sub panels, if not is there a required size ground bar that must be met for the listed panel?

The total run is a few ft less than 60'.
I planned to run #4 AWG THHN/THWN Building Wire in BLACK (lead)/BLACK (lead)/WHITE (neutral).

& #6 AWG THHN/THWN in GREEN (ground).

This will be in 1 1/4" sch40 pvc electrical conduit dug 18" under ground level.
No more than 270 deg. in bends total (90 / 45 / 45 /90)
The exit point unfortunately comes up at the edge of a concrete slab that is against the garage (its the path that lead to the front door from the driveway). I haven't seen anything against this but felt it should be pointed out.
Anything I missed or should change? Any constructive criticism, pointers & shared knowledge will be greatly appreciated. Thanks
