Just my thoughts, but I would get the bucket. A plastic bag will collapse in a heavy rain and force you to possibly get very close, too close, to an energized connector. It might even collapse to the inside of the base. As a small measure of protection wear rubber soled boots or rain boots when near it and don't touch 2 metallic items with both hands or body parts letting yourself become the path to ground. Better yet, just put a bucket over it and stay away from it. Sounds like you won't see any repair person for a couple of days at least. Good luck.
