OSB lower walls-wiring

[wewiserangers]

Planning out the details of a new shop. The interior will be white steel liner with the lower 8' portion of the walls done in osb. I'm looking for suggestions on how to do the wiring. Behind the wall or exterior in conduit. I'd love to see some pics of how you did yours.

I did a mix.
I have OSB from 4’-8’ with metal W panel from floor to 98”. The extra 2” makes a trough of sorts in which I ran MC cable in I made some brackets and mounted a junction box at the top, ran my MC to it then ran MC behind the metal panels, notching the OSB where needed. My outlets are at 48” . For multiple outlets, I ran MC at the 48” height to subsequent outlets.

I definitely wasn’t the most efficient, I mounted all my OSB then mounted my metal panels then removed the metal panels to cut the OSB to mount the box to the horizontal purlin. I used my 3 plane laser to line up to the box, installed the metal panel and transferred my lines to the metal panel.

My walls are all a mix of OSB and plywood (got a lot for free at the time). I had initially run my electrical inside the wall, but as garages evolve you end up moving things or adding new tools. So now my wiring is 50% in the wall and 50% surface-mounted in EMT.

If I could do it all over again, I'd surface mount everything in EMT. Makes it easier to get a tighter building envelope instead of sealing around a bunch of boxes.

OSB is flammable.
If the finish is OSB and flush mounted (behind the wall) the box needs to be flush with or extend beyond the OSB.

if you use OSB, consider using one of the commercial fire retardant products ...Universal Fire Shield! (or) the other option is Fire Retardant Plywood $$$$
