Outlets - Commercial Kitchen Backsplash

[Bradatm]

Another odd electrical question. We added a tile backsplash in the commercial kitchen. There are outlets there and we just put some spacers behind the outlet screws like normal. This makes it flush with the tile.

The electrician who did the original work said he needs to come in now and I think he said "arc extender" or something like that. Best I can tell is he wants to add a metal box extender so the box is now flush with the tile? He said it is code.

I've never heard of it before and I haven't seen it in any code requirement. Can we just use the spacers or do we have to do his plan which would mean trimming numerous tiles?

Thanks for any help!

This question appears at first glance to be a simple question about code, but a deeper examination shows us that the work involved (reworking the receptacles after installing the tile) was done by a non-electrician, making this a question about DIY work by unlicensed personnel. I am therefore closing this thread with the admonition to avoid the performance of electrical work by unlicensed personnel, whether or not such work is permitted by local codes in your area.
