Assuming I remember correctly, the fill capacity is 40%.

Phil, this is rigid conduit, which can be very difficult to work with and a bit more expensive than EMT conduit, which, if this is an indoor installation, would probably be a better choice in this instance.

Solder and heat shrink tubing are your friend.

Only if the NEC says they're your friends. Check your codebook before you settle on a splicing method, and never put a splice in a conduit.

Again, check your NEC codebook to see if the product you're considering can be used in your venue. Also, Wiremold products are more expensive than EMT conduit and standard junction boxes. Given the $2000 budget, I would think twice about going this route.

For this application, wiremold would be a nice choice if local code and the NEC allow it. My posting of the conduit access ports was just a suggestion for someone who doesn't want to have to bend conduit. I didn't realise it was for rigid conduit. My electrical installations are so few and far between (and always industrial or commercial) that for bends I either use flex or J-boxes (junction boxes).

Thanks CW. I heartily agree. I should have specified soldering to the connectors on the wall plates at each end, and any splicing done "in the middle" (I still say solder) should only be done in a junction box that is proper for the application/situation and only if code approvable. Sorry.
