It's easy to explain. Some places try to rob the EC.

There is 2 different things that are often confused:
Electrical License
& Electrical Registration

Why it is 2 different things has no good reason except to collect $ in more then 1 way.

Some places do understand the $25 max registration if you are unregistered. Others try to ask but I send a copy of my registration along with the statute. Some just get me angery by saying "we don't care, you want to work here then pay us this". They understand that very few business want to go to court fighting over an unnessisary fee under $100.

The real trouble is no state wide rules, licences, etc.
