I’m watching this arborist on YouTube and they have a truck with a bucket on an arm so they can reach heights without climbing. On/after a rainy day the bucket will accumulate water and they mentioned they can’t drill a hole to drain because it will compromise the grounding.
My understanding of grounding/electricity doesn’t explain this. Can someone help me understand why this would make a difference?
Edit: I get it, I/he should have said “electrical isolation” instead of “grounding”. Either way, a hole allowing a stream of dirty water seems to be the answer here. Thanks 🙂

Not an arborist, but I’m pretty sure they call the people working on the ground “groundie”.
Could it be that they meant water would drip from the buck down on to the groundie?
I see no electrical reason to not make a hole for evacuating rain water. Grounding (or isolation) of the bucked does not depend on having a solid structure.
For an insulated bucked designed for high voltage work, there is a point in not drilling a hole as it would void the design/approval rating of the bucket. Breaking through the layers of the bucket will change how it behaves as a high voltage insulator. Might be dangerous might be not. But it would not be up to code. But for an arborist I can’t imagine that a hole would really make a difference unless they are also working on power lines.
I guess they may be renting trucks which are also approved for high voltage work and thus without drainage.
