I have an unfinished garage which I am looking to upgrade the service to.
Currently it is 15amps running through some difficult to access sub-ground conduit, but if I run the band saw plus the vacuum and lights, the breaker trips. I'm not very familiar with Canadian electrical code, but I am guessing that the main wire picture below is probably 14/3, and I can't imagine you would run more than 15 amps on that?
Snaking/Fishing a new wire might prove to be very difficult as there are several 90 degree bends, and the entire line is behind drywall up to the box. Is there any hope here or am I doomed to shell out some serious cash to get the work done?
Here a photo of where the main wire runs in (the largest of the 3)
