Rewiring garage: under or over ground?
Hello,
My home is being rewired (to 100 amp) to eliminate all of the knob and tube wiring. I also need to have my 2 car detached garage rewired. It is approx. 50 ft. from the house. I need lighting and some outlets. It will be used for recharging the mower, a soldering iron, a few power tools, etc. I would like to add a door opener in the future.
I was first told the wire would have to be 2 ft. deep, then later was told 3 ft. deep. 50 amp service has been suggested w/a breaker box wire running overhead to the garage. I am worried that the children may knock the wire down when playing ball in the yard. I have been reading through your responses and realized there is a lot to all of this, much more than I thought or know anything about: different conduits, wires, sun resistant wires, and so on.
Questions:
Is one method better than another?
Is one more cost effective?
What materials should be used?
Is 50 amp sufficient?
How much should a job like this cost? (I am willing to dig the trench if underground is recommended)
Thank you for all of your help.
