Lost a topic I was hoping to get an answer from

Looks like I lost a topic that I was waiting to get a reply on about something I think could be important so thought I'd create a new post and ask about it. Long story short is it Ok, meaning safe to run wiring in the ceiling over another wire, you know like one actually lying across another? Both are 12 gauge wrapped (The yellow stuff you buy at any Lowes or HP).

I surely hope so. There is wiring like that in my basement, not to mention places where there are 2 wires sharing the same hole that is drilled through a joist. But mebbe NEC code was different when my house was built 30 yrs ago.

I'm not a NEC code person but form an engineering standpoint,
it would be quite safe. Each wire has probably 600V insulation so between them it can withstand 1200 V to each other. The other problem with packing wires is overheating. When run at right angles it maximizes the free air heat dissipation and minimizes the close contact packing that can cause overheating of multiple wires carrying large currents.

Crossing wires

Perfectly safe and within code with the type of wire you're using.

Running two power lines next to or over each other are not a problem. I generally try not to mix high and lower power (phone, cable, etc.). This is more from a signal standpoint and not a safety issue. I've had noise induced in lines from mixing a 60 Hz powerful magnetic field too close to other conductors.

Thanks

Hey thanks for the good news guys. I've been a little worried ever since I read and evidently misunderstood that Post I lost. Sure appreciate the replies.
