I work for a manufacturer of mobile medical trailers. We are working on incorporating a new "snap lock" design for assembling our trailer walls. The construction of the walls makes coventional means of securing conduit boxes for light switches,outlets and junction boxes impractical. We would like to use a tape or adhesive to secure the electrical boxes to the trailer walls. Could not really find anything in the NEC for or against this type on installation. Looking for help to see if this is ok to do. Thanks.

Re: Electrical box installations
Art. 314.23 requires boxes to be rigidly and securely fastened in place. I haven't seen any adhesive capable of doing that, although there may be some out there. There is an adhesive that bodyshops use to glue metal to metal, however, I'm not sure it will work in your instance.

Re: Electrical box installations
Arcman, just out of curiosity, are you going to have these units third party tested.
In the city I primarily work in, any mobile MRI, lithotripsy, tactical imaging, etc... must have a UL, ETL, or some listing as a unit.
I would think this could come under art 551.
If this is the case 551.40(B) may be a problem. If anyone could come up with an approved velcro installation,they would be a wealthy person.
