No Drip Loop

[chris kennedy]

Did a "work with" with POCO. Three conduits nippled out of the top of an ATS into an open top transformer vault. The conduits are above energized part in the ATS.

I requested POCO leave a drip loop in the vault and went to work in the electric room. Came back to see the conductors leave the nipples and go straight up to a uni-strut rack.

Again there is no lid on this vault.(just chain link) My concern is rain running down the cunductors and into the ATS.

Any ideas on how to seal this?

Thank you
Chris

Maybe I am having a hard time picturing your setup- maybe not- is this exposed and if so why no weatherhead or some other means to keep dry?

There is a seal kit available that POCO probably has available to them. To oversimplify, it is an inflatable "bag" that will seal 100% around the conductors. It is made by Raychem. It is inflated with a CO2 cannister.
