    Default Junction box extension of wire

    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

    As long as wires are terminated in accessible boxes you should be fine.

    I don't have a pic with me, but the run came out of the ceiling right above where we planned, we were going to run in the wall and then have the junction box in the wall, and then conduit runs to the sides, but since the run was short, we ended up with just mounting the junction box at the ceiling and will run the conduit and quads from there..

    I take it this is just one 120V 20A circuit.

    New Code requires all such circuits must now be GFCI protected so, the box you're talking about would be a good place to install a GFCI receptacle. Feed all your new receptacles from the terminals labeled "load".

    I can get more specifics when I get home, but the box that was installed looks like this one..



    the run is on its own breaker and will only run 2 quads I think is what they told me. If I could get 3 quads it would be better, but I could work with 2..

    Ill try to post specifics later with breaker size, wire gauge and so one to see

    Now I'm confused.

    Each receptacle yoke (which can have up to two places to insert a plug, called duplex receptacles) counts for 180 watts.

    A 20A general purpose receptacle circuit can provide 2400 watts of non-continuous power. Or, 13 yokes (6 quads).
    Likewise, a 15A can power 10 duplex receptacles (5 quads).

    If powering continuous loads, which run continuously for over three hours, the wattage for a 20A circuit is reduced by 20%, so it drops from 2400W to 1920W (5 quads).

    For dedicated loads, the circuit should always provide at least the amount of power for the applied load and never run overloaded.

    Multioutlets: long strips containing for example up to five single receptacles, in a location like a home workshop or garage where it is unlikely all the receptacles will be used at the same time, shall be counted as only 180Watts for every 5 ft in length. So, you could have up to 66 single receptacles on one 20A circuit along your garage walls, if on strips.

    Have your electrician refer to NEC 220.14 (H), (I).
