I am quoting a job to install a few recept. and a couple of flour. lights in a race car transporter. The power will come from a portable generator (6Kw).I plan to install a 60a MBP inside the transporter and a flange mounted male twistlock recept.outside to hook up the generator. Do I need to bond the ground from the generator to the frame of the transporter? And also it would be very inconvienient to drive a ground rod everytime he uses it, so should there be a ground strap installed from the transporter to the frame of the gen?
 
Re: Race car transporter

I would think a four wire feed from the generator to the trailer with a bonding jumper at the generator.

Is there shore power at some tracks, if so you might want to find out what the standard outlet configuration is.

No need for ground rods if you follow the rules that Tom pointed out.

Any chance of mounting the genset on the trailer?

Point taken, but I did not give any code references for the trailer, JMO. :D

The generator I am with Tom on the NEC references.
 
Re: Race car transporter

The panel would be a main panel with the neut. and the ground bonded.Correct? I would treat the frame as a grnd electrode and bond the neut. and the grnd from the generator to it.Correct? I don't have my code book at home with me to look up the code ref.
 
Re: Race car transporter

Wayne, being that you are in N.C., is this a Nextel car carrier?

If so, you may get Ed MacLaren to make a personal apperance to help you. :)

Just kidding, I do know Ed is into it.

Roger, if Greg Biffle hadn't got caught speeding on pit road, we might have had a Ford victory at Daytona on Sunday. :D

Wayne as Charlie has said the trailer itself may well be outside the scope of the NEC.

With that said I would not set this up as you describe. I would not bond the neutral to the trailer frame.

If you look at 551 Recreational Vehicles and particularly 551.45 Distribution Panelboard, you will see for park trailers the code requires the neutral to be isolated.

I am not saying this code is enforceable for your car carrier but if it was me I would follow the appropriate rules of the park trailer article.

I would make the bond at the generator, this will bond the generator frame to the trailer frame through the EGC. (Four wires between generator and trailer)

At the trailer make sure to bond the trailer frame to the grounding bar of the panel.

There may be other issues but the one that sticks out to me is if you bond the neutral at the panel in the trailer they would be no code compliant way to hook up to shore (permanent power) if that ever comes up. I think at some point that is likely, maybe at the home base.

I would use the attachment plug used for a park trailer 125/250-volt, 50-ampere, 3-pole, 4-wire grounding type.

Wayne I am not an engineer that is just my opinion and hopefully others will post if my opinion is off base here, I would not want to see any one get hurt. :eek:

In my mind it just makes sense to use article 551 as a guide even if not truly enforceable for your job.
