How do you power a detached garage?

Run the conduit from the garage to the main panel box. If concrete has not been poured in the garage, run conduit down into the ground on the inside of the garage. Use a 90-degree sweep connector, instead of a sharp 90-degree connector, to make it easier to pull the wire through.

How many outlets can be on a breaker?

I’m ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker.

What wire size do I need to go 100 feet for a 60 amp service to a workshop?

My rule of thumb for a service connection is to use the largest conductors that will fit. If 6 AWG fits, then use it, but 8 AWG would work. I know, it’s only a 100 foot run, but your workshop may eventually grow to have more power loads, so a larger service conductor provides a better power factor (cooler wires).

What size breaker do I need for a detached garage?

50 ampFor most garages, you will want to use a 50 amp breaker with 8/3 wire between the two buildings to handle the load. Install a sub-panel with its own main breaker so that the power can be shut off inside the garage for servicing the breakers in the panel.

What size cable do I need to run power to my garage?

Well 1.5mm2 should be OK if that is all you require, but use 2.5mm2 to be safe. The distance you need to measure is from the supply to the garage. For a 30metre run even 2.5mm² would be pushing it. If you are installing something like this, now is the time to future proof it, so just think about possible future use.
