my electrical plan - is it to much for 60A service.

[Boones]

Hi guys, I need some advice from those who are familar with electrical.

I have been building/ remodeling a garage and I am at the point where it is time to rewire/ wire it. It is now a 24x48 shop (2 24x24 garages with a 12' opening between the two).

The previous garage had a 60A service running from the house. Due to various things i am going to keep the 60A service to get the final permits on the garage. it had a 60A fuse panel with 8 spaces for breakers. it was missing the front panel so I bought a new 100A panel with 20 spaces (room to grow later on) and I also bought a 60A breaker to bring the panel back down to a 60A service.

Since it is basically two 24x24 garage I am thinking of wiring each section the same with the left bank of breakers for the left 24x24 section of the garage and the right bank for the right 24x24 section

Here is what I am thinking of doing
Left garage section:
qty 1 20A breaker with a light switch to run 4 8' (32 watt) lights
qty 1 20A breaker for 7 to 10 receptacles (110v) - I have thought about breaking this into two 20A breakers for 3 t0 5 receptacles, one for each of the two walls that wil have receptacles
qty 1 20A breaker for garage door opener (MasterLift 3800)
qty 1 30A breaker to a 220v receptacle (for compressor)

Right section garage
qty 1 20A breaker with a light switch to run 4 8' (32 watt) lights
qty 1 20A breaker for 7 to 10 receptacles (110v) - I have thought about breaking this into two 20A breakers for 3 t0 5 receptacles, one for each of the two walls that wil have receptacles
qty 1 20A breaker for garage door opener (MasterLift 3800)
qty 1 30A breaker to a 220v receptacle (for future lift)

for outside lights
qty 1 20A breaker for outside lights (qty 3 decorative lights)
qty 1 20A breaker for outside motion detector lights (one over each garage door)


What do think, to much for what i have, are the breakers to large for some applications (like the garage door openers?). would appreciate any input from those that know whats going on.

thanks in advance for the advice

I would use 1ea 15A breakers for the outside lights. I would also put both door openers on the same 20A circuit.

Don't forget the emergency lights on the lighting circuits.

The 60A service is probably quite adequate.

youll save some cash by going to #14 and 15amp circuits on your lightly loaded lighting circuits.

Do a load calculation. Then you will know exactly how much power you need. It's not difficult. You can probably find forms and instructions online.
