This why some say no good deed goes unpunished.
What made it worse was this was on a service upgrade and the Poco guy told the customer (I wasn't there) this was against code and I shouldn't have drilled a hole in the enclosure either, so you can imagine I got a call about it.
I explained to the customer the reason for the tail but told them I would come and remove it. (I asked if it seemed like the guy was drinking - I guess he's never seen the little KOs in the bottom of the enclosures).
Does anyone leave a tail like this?
I thought it (or something) was required per 250.94 in situations like the one pictured.
