A dedicated 20 amp cable must be run from the circuit breaker panel to the
location of the outlet. The easier and quicker it is to do this, the less it
will cost. I would suggest getting another estimate

Hi
I just moved to Seattle and we bought a treadmill which we've kept in
the garage. Now the garage has a 15amp circuit but the treadmill needs
a 20 amp one. We asked an electrician to give us a quote to change from
15 to 20 and he has quoted $600 for the wall closet to the door and
$900 for a wall further.

I am novice at this, could someone tell me what would be a good price
to pay for this?

Thanks
Rashmi
