Wow, at least we have an honest one, here.
Here's the scoop. Let's say you're at the swimming pool and suddenly you get a headache.... for whatever reason. The sun, the bright lights making you squint or just a bad day. You go to the concession stand and ask if they can give you an aspirin or some other headache pill. No, they can't. They can't ask you questions or give you any advice on your condition. However, they can sell you some aspirin if it's on the shelf to be 'SOLD'. They cannot take something out of one of their purses or on the back counter. That's illegal. That's prescribing, which they don't have a license to do. However, if it's on the shelf for sale, they can sell it to you, but you hafta do all the work. Let's say, they don't have anything to sell you and you walk down the street to the pharmacy. Guess what, that counter girl cannot give you anything either. You can only buy what's on the shelf and ask them.... How Much ??
These electric codes are much the same. You can suggest to someone what to do, but you cannot administer any fixes or make-overs. It's technically, illegal.
Do people do it, much like yourself ?? Yep, you bet, they do and that's why the codes and laws are getting more and more strict..... because of people like you sticking their nose
in where it shouldn't be and getting innocent people in trouble or worse..... hurt.
It might not apply to you on this one, but the odds are not in your favor. Why do you suppose so many big shops have so many laws and codes they hafta follow, but you little guys think you are exempt from the same conditions ??
You want to alter a cabinet and regardless what you call it or don't call it, you want to do something which contains electrical wires, ballasts, lamps and other things..... but have no clue as to the safety or where anything is, but you want to put a rain gutter on a sign and create holes, possible shorts or better yet, drill a hole through something.
Had you at least asked about the ballasts being mounted on the top raceway or where would you turn this off if there's no disconnect or would I cut it at the main...... perhaps, you would've sounded concerned, but no, you're not at all concerned for the important parts of this venture.... are ya ??
