Zog......It seems many EC's do not concern themselves with the OSHA rule, as many EC's in this forum have said they change services hot, not because they have to, but because it it is less time consuming, therefore less costly.
I was asking whether EC's charge more when they have to get the Utility company involved, and as they stated it cost more in their time, so it is an additional charge. As they stated they charge less if they change it hot of thier own volition and that seems to be their preference so they can charge the least.
The reason I was asking was because in my area, it is standard operating practice for EC's to change residential services hot, and since I was not going to allow that for a service change I have coming up, I didn't want to be surprised at getting a cost adder for requiring that they do it cold.
