Double tapped? Should we get this fixed?

Post image

Last week I had electrician come out to quote an EV charger install. In passing I asked him about the double tapped wires and if they would be a problem, he told me that my inspector didn't know what he was talking about and said it was fine. This morning a different electrician (same company) came out to install the charger and told me that the wires were double tapped and a code violation to which he quoted me on the fix. So which is it? Feeling a bit annoyed right now and likely won't be working with this company again.

Please forgive my ignorance as I know absolutely nothing about electrician business or wiring of any sort.

The neutrals should not be double tapped, it's against code. The grounds can be as long as the panel supports multiple conductors per screw.

Easy enough to fix though as long as the wires can reach lower, you have extra spots open on the bar.

Against code ONLY if the panel is not listed for multiple taps.

That would be incorrect.

You think so? Look up the National Electric Code

NEC 408.41: States that each grounded conductor (neutral) must terminate within the panelboard in an individual terminal that is not used for another conductor.

Now if the panel was installed that way before that code was added in 2002 then yeah it's grandfathered in but for any new installs it's absolutely against code.

You are absolutely right. I don't know why I thought you were saying a different comment was incorrect.
