Insulate conduit for main?


Need to upgrade service but want a simple fix for now. Pigtail comes in through roof, through panel, out to meter and back to panel. Just about every large conduit in the panel gets condensation dripping once it gets real cold out. Can I spray foam in the conduit to seperate the warm inside air from the cold outside air to stop the dripping?

No not foam. You need what is called duct seal. It is made specifically for electrical conduits.

Is that a spray ? I'm not going to push anything in with all that unfused wire running in and out.

Call an Electrician that has the proper gear. This is something that should have been done at install, not something that you the home owner should do without the proper training or protection gear.

Will do! Didn't know if it was a DIY job or not but sparky will get paid before I get killed.
