Might be dumb questions, but I'm looking for some info regarding getting
electricity and gas out to my garage. I've posted this elswhere, but still
looking for some feedback.
I'm located in Calgary, Alberta, Canada. My garage is 24feet by 32feet, with
three bays. I'm considering closing one bay off from the other to for use as
a workshop. The other two bays will have minimal power needs. My house has a
Run from breaker box in basement to garage is about 70 feet. I want to be
able to use 120v and 240v tools. I'll be the only one using the workshop, so
most tools will be 120v with a tablesaw being the most power hungry, BUT I'm
hoping to get a low power (30amp?) mig welder at some point.
Run from gas meter to basement is about 80 feet. This is going to be used to
heat the garage.
I'm also considering some method of running a waterline out to the garage
for an outside faucet to water the garden. It can get VERY cold (-40
degrees) here. It can get below freezing almost any time of the year so I'd
rather avoid something that needs to be manually purged. I'm considering
running a 3/4" rubber hose inside a conduit. The rubber will allow for
expansion if there is a freeze and the conduit will keep the hose from being
crushed. This would be at the same depth as the gas and power lines.
About 30' from the garage I will be making a 30 degree bend. Other than
that, the path will be straight.
I will also be running one RG6 cable, two Cat5e cables for alarm & phone and
two Cat5e cables for networking.
What I'd like to know is...
- How deep and wide of a trench do I need to bury all of this safely? I
don't think there is a minimum distance between gas and power here in
Calgary, but I haven't looked into that.
- What gauge wiring do I need to use and what size breaker in my basement? I
figure an Edison circuit from two 30amp breakers on my main panel.
- Do I need to tie the ground from my main panel in the basement to my panel
in the garage, or do I need a separate ground stake at the garage?
- Should I just get the a gas contractor to come out and dig the trench for
the gas line and leave it open to drop the other lines in? (ie, should I try
and dig the trench to save some costs?)
- Will my ideas for the water line work?
Any thoughts or comments are welcome!
