Ok guys, I got into a pissing match with a “master” electrician over the phone and he said this was correct installation without a problem and I said it was not correct and this isntallation and connections are not made to facilitate two wires. He told me that he would send me information and I am still waiting on it…
Here is the set-up
A gas pool heater was taken out and an electric heater was installed. They ran a disconnect to the main panel and “double tapped” it.
Am I wrong in calling it out? Does anyone have the code reference where it states it is wrong. House was built about 15 years ago, if that matter any.
This is where I disagree. I don’t care who you are, wrong is wrong. When my client goes to sell his house, I want it to be proper. I often argue with tradesmen no matter what they put in writing. Of they show me specifically where it is in the code book, then I will back down.
I truely believe it is these instances which gets me more business, especially with the high end client. This guy has been the owner of a large company for years. I don’t think he has been in the field for years.
When this happens I tell my client my point and give him my specifics and then let them decide.
Hey we all know the picture is wrong and so does the Electrician so he will never put it in writing anyway…catch my drift?
Personally I doubt the guy on the phone was anyone other than the seller or his buddy.
That provision does not address the improper connection. The lugs/terminals must be listed for multiple conductors. In addition, the conductors are generally required to be the same size when multiples are allowed.
The tap may be correct. It is the method being used to terminate the tap that is incorrect. As many others have said the lug needs to be listed for multiple conductors. If you read the label you will see where it says 1 conductor.
That code section is for tap conductors and has nothing to do with terminating two conductors under a lug that’s only listed for one conductor. Here’s a photo of a lug listed for two conductors. You can see that it’s clearly marked.
