  • Slightly OT, auxiliary power from bobcat

    I've got a Bobcat 225NT that is used frequently for temporary power when I am not welding with it. My question for the electricians on the board is how can I make a pigtail/breakout box that can use the full 9500W output of the welder in a NEC and OSHA legal way. I'd also like it not to cost an arm and a leg either.

    would it be legal to run 8-4SO cable from the 14-50P to a metal box with multiple receptacles cut into it? I would like to use mini "pin" circuit breakers to protect each circuit.

    Temp power-

    To power up yer house?
    Transfer Switch

    Don't wanna run a couple extension cords?

    You get the full output from the Bobcat through all of its receptacles or through one- the 14-50R.

      No, temporary power as in providing power for a jobsite.

      You can't get even close to the bobcat's full power output through the 2 20A 120V circuits on the face of the machine. This is why I'm asking how to make a compact and portable breakout box connecting to the 14-50P that will stand up to an OSHA walk-through

        Sorry about that- looked at the manual- I assumed it had more outlets


        I would bet nothing home brewed/ cheap will pass OSHA.

        Seems like it will have to have GFI.

        Any used Distribution boxes in yer area?

          You can see one I used off the Trailer's genset sitting in the background

          Same 14-50 plug as yer Bobcat and the Box connector on the other end- can't remember the name.

              Yeah, something like that would be perfect... I just wish they weren't $500...

                An electrician is the only one allowed to supply power to a job site that is inspected. You start doing this and one might cut your cord, He will come talk to you first. Now if you are the only one using the power, well you "might be ok".
                I was an electrician in the past and had to inspect all the power cords that others had brought on site. OSHA made me the one who had the power to do this. any bad cords, I just told the guys to leave them in the truck. My boss wanted the cords cut, I aint no butt head.

                This is true for the good and bad
                that life puts out.

                  With all due respect Red, that's not true. We, as the GC are typically contracted to supply temporary generated power until the utility based temporary power is paid for by the owner and hooked up by our electrical subcontractor and the power utility.

                  As one of the Job supervisors in my company, if an electrician starts chopping up my cords, he's going to find himself off my site and a back charge made to *his* boss. I've been in this game 15 out of the 63 years my employer's been in the business and it's taught me once thing... "he who holds the money, holds the power" & the electrical sub's money runs through ours.

                    From what I'm hearing now, also, OSHA no longer allows assembled cord caps. meaning all plugs and connectors have to be molded onto the cord from the factory. Maybe this won't apply to a NEMA 14-50P on the Bobcat, but you might want to make sure.

                      As long as everything is safe and with code and follow OSHA guides, there is no problem.

                        Is this true that the outlet on the side (in my case its a nema L14-30)will supply all of the 8000 watts that the genny puts out. I need to hook this up to my house for aux power when the lights go out. The machine is a Miller Bobcat 225G 8000w. It has 6 outlets on the front (4 15a 110 and 2 20a 220) and then the one (l14-30) on the side. Thanks for the help, B

                          Rock,
                          you should be able to utilize the L14-30
