There is a 240/120 volt single phase panel board with a 200 amp main circuit breaker incorporated in it in the basement. The homeowner wants to put a 60 amp panel in his new garage where there will be 1-30 amp, 2-20 amp and 2-15 amp circuits. Can this panel in the garage be main lug instead of main breaker? This garage is detached. Thanks Denny

Re: circuit breaker panels
How many spaces will remain unused for future breakers in the sub panel?

Re: circuit breaker panels
Your allowed more than i service panel but they must be grouped together.Double lugs at meter is allowed but the service feeds may need to be upgraded.Dont forget the panel in garage will now be a sub panel and require its own main breaker and ground rod.A main breaker panel will be needed beside the 200 amp also.It will be far cheaper to run a 60 or 100 amp breaker to existing panel and then run to the garage.Depends on if that 200 is needed to carry the house,usually it's not.
Either way the panel outside in garage is a sub panel so split neutrals and grounds.4 wires to garage plus ground rod maybe 2 rods depending on AHJ

Denny,

Denny,
225.32 requires that the garage have a means of disconnect. 225.33 permits up to six breakers to be used as the means of disconnect at the garage. As long as the feeder to the garage panel has an overcurrent protective device that has a rating equal to or less than the panel rating a MLO panel at the garage is code compliant.

Re: circuit breaker panels
Don's post has the code references, 225.32, 225.33.
The garage requires a disconnect, but if you have six or less throws (six single or six two pole breakers) than a main disconnect for the panel is not required and a MLO panel is permitted.

Re: circuit breaker panels
i would install a 60 amp disconnect prior to the panel outside the garage.

Re: circuit breaker panels
Be carefull if you use ML if it is a 6-12 it won't pass as it could be added to.
For the price of a 60 amp breaker it would be worth having a few extra space for the future

Just back feed a 2 pole 60 for the main easy and cheap

Re: circuit breaker panels
Jim,
If it only has six breakers at the time of the inspection, the inspector would be way out of line in red tagging it. The inspector can only inspect what is installed, not something that may be installed in the future. There is nothing in the code section that says you must not be able to install more than six breakers in the panel. It jsut says that you can't have more than six means of disconnect.

I thought under 250 (grounding) additional gnd rods are not required? Ive always understood that gnd rods must be prior to the first discon means?? 250.30 B1

Re: circuit breaker panels
Actualy this
If there is no other conductive path to the garage there is no need for an EGC.
The ground rod yes.
See 250.32(B)(2)
