Issue of adding rain covers to outdoor motor junction boxes
Thread Content
During the maintenance of the motors, it was found that the wiring boxes of the outdoor motors were not properly sealed and there were signs of water intrusion. Please discuss whether it is necessary to install rain covers; whether any petrochemical plants have already installed such covers on a large scale; and whether installing rain covers would violate any standards, specifications, or regulations
We are a chemical manufacturing company, and all outdoor motors have been fitted with rain covers, with very good results.
The motors in our facility don’t have rain covers, but they are all explosion-proof; I’ve heard of no cases of water getting inside them.
Let’s see the requirements; of course, it would be great if it were added
Are you a factory of Sinopec or CNPC? I heard that there are some regulations or rules that prohibit such practices, and few Sinopec factories do this; as for the exact reason, it’s not yet clear
No. Follow the regulations of your industry; Sinopec has quite strict unified management requirements.

When placing an order, you can ask the supplier to include a rain cover for the motor; actually, it can also be added later – for vertical pumps, simply replace the motor cover. Last time, we provided free replacement rain covers for motors to our existing customers: victory:
All outdoor motors have been fitted with rain covers, and the result is excellent; that’s what we do.
Only our motor has a rain cover; everything else is exposed to the elements
Are there any styles or manufacturing diagrams for rain covers for reference? Thank you!
