    So, Turns out I needed one more Contactor After all.

    So here is the update,

    [​IMG]

    I then built a remote control for the Box, this will control the output relays.

    Simply Turn the key on to Arm, and the light will illuminate.

    I also installed a manual bypass for this on the box itself, if I want to keep it on.

    [​IMG]

    And with this mess it is almost 100% wired, all functions work, so now it is time to spend a day with some Zip Ties and clean her up.

    And here is a VIDEO of me running the hell out of a DC compressor motor :}

    Got the output Stage completed and E-Stop Circuit wired up.



    [​IMG]

    Got the Main output breaker mounted and wired with 4AWG. it is a 100Amp breaker.

    [​IMG]

    Here is the E-stop and Variac Knob and breaker placement.

    [​IMG]

    And the Back of the unit, Few random wires left to connect. Was tricky trying to keep the power wires as short as possible.

    [​IMG]

    And the Entire unit.

    I hope the Next Video will be with it completed.

    Haha I actually ran out of room, so I have to build an external current limiting array.

    Need to find a small enclosure now...

    Work has been crazy so not much progress,

    But got a little done tonight,

    [​IMG]

    So brought the punch set home for a few holes and picked up some power cord for the project (10AWG/4Conductor) about 25'

    [​IMG]

    Punches make life so easy haha

    [​IMG]

    So I will try to explain this,

    the normal looking 120V Plug is so I can use a remote ground as well as remote 120Circuit ( For the control side ) if I need to pull massive power on the main line.

    the large 30Amp twist lock, is for the remote Current limiting resistors. This will allow a quick connected of 3 External loads.

    [​IMG]

    Installed a 50Amp 'Welders' Plug that fits most homes. I also ran an external ground, for allot of welding plugs do not have a good ground.

    [​IMG]

    And everything plugged in for a test run.

    I also put a large strain relief on the Main power line, I may make this a plug and socked down to road as well, so it can be removed for when I need to relocate it.
