All:I'd like to get a feel for how many people use 10 gauge THHN for speaker wire when you have conduits in place. Use of this has come up with some clients due to its much less cost. We have used it in the past out of necessity for some stadium type installs but it seems like it hasn't come up on this list much and I'd like to know others thoughts.Regards to the list,Roger
Stranded THHN should be fine for speaker wire in my opinion. The only concern I would have is the AHJ not understanding it is for a low voltage load and question a jbox with a panel that had line and speaker connections but no high/low divider. Sent from my iPhone using Tapatalk
Ideally do the pairs need to be twisted together or can lets say 8 wires be pulled through one conduit without a problem?
From a cross-talk perspective, you're better off with the pairs twisted but realize they'll occupy more pipe space when they're twisted. I've done both using twisted pairs wherever I've had room and dropping back to untwisted THHN wherever I was too tight for space.Toodleoo!Ron Hebbard.
Thank you all. So, in summary, if THHN is used, Twist it if you want and can afford the space in the pipe. Don't bother twisting if you need the space in the pipe- but either way, quality (crosstalk or common mode etc) of the signal should not be an issue when used in reasonable lengths v gauge.
