600 vdc inside house conduit

[9mile]

I've been told I have to use metal conduit. If so do I have to use rigid or can I use EMT if it's buried behind a wall.? Also with 1 inch conduit suffice for 2x 10 AWG conductors plus a 10 AWG ground wire?

RMC would probably be the choice if outside, EMT should be fine.
1 inch conduit is more than adequate (16 10awg max); 1/2" would be fine.

If you're behind a wall inside, why not use romex?

Is Romex code for 600 volt DC? I read somewhere that it has to be inside metal conduit. That's why I'm looking to The Forum for help!

DOH, somehow I missed that little tidbit. My bad. This may help you
according to the spec sheet it is rated for 600 volts. I don’t think there is any difference between an AC volt and a DC volt

Yes, I believe so.

the solar installers in Ca use fmc alot of the time

I belive you want stranded wire for Dc applications. most romex is solid.

Again, I am not an electrician ,but based on what I have read for low amp applications like a solar feed it doesn‘t matter. I rely a lot on Mike Holt forums for my knowledge (limited though it may be) and would refer you to this discussion

Solid or stranded for dc

This is so petty but I'm about to quit my job over it. I did a solar install. I ran 10-2 w/g solid uf wire from the e-panel to the solar panels. I'll not mention the load on the wire or the distance or the temperature because I don't want to side track the issue, all were well within the...

For high amp DC feeds (battery to inverter) I have heard that stranded is better due to the increased surface area provided, but I will be damned if I can find that reference, sorry
