Spray foam insulation and wiring…

| Posted in Energy, Heating & Insulation on
Their are limits on the number of conductors that can go in a given size of conduit, and it’s my understanding that these limits are imposed due to heat concerns.
So I’ve been wondering: How can you spray foam in wall cavities (and other places) where it will completely encapsulate long stretches of romex-style wire?
I mean, shouldn’t that create more of an overheating concern than putting too many wires in a given size of conduit?

Greetings JDLee,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again which will increase it's viewing.
Perhaps it will catch someone's attention that can help you with advice.
Cheers
No more of a problem than another other type of insulation.
The insulation is not a source of heat. But bundled wires each wire does generate heat. So if you have too many is a tight area you need to reduce the maximum amount of current the wires can carry.
