Earlier this year, I had 2 lines run from the breaker to the garage to have dedicated lines for my compressor and to add more outlets for power tools.

Due to funds at the time, I was only able to get 2 rolls of 100ft of cable to make the run from the back of the house to the garage, the first drop was fine and made it to the right place and got the compressor connected.
The 2nd run made it to the right place but not down the wall far enough, so was told that was ok, that the junction box could be mounted as it was on my ceiling and when I could afford to continue, they would just add the appropriate cable from that box down to the quads I needed installed.

Is that correct? Just looking to be informed and have some knowledge of what will be done when its done..

thank you
