Here in Michigan we have been working under the Michigan Residential Code for one and two family dwellings . In March we will be adopting 2023 NEC.

Prior to the adoption we had no arc fault requirement or Emergency disconnect.

Looking like will soon be adding about $2K to the base wiring cost minimum.Then with 240V cord and plug devices needing GFI , another $300 and whole house surge protection could easily see about $3K overall.

Yes, but that is only about 1% increase for all the safety and well being of your customer.



Have fun with it.😀
 
Yes the new requirements are expensive. I just upgraded a 40 circuit 200 amp service to a 40/80 200 amp service but didn't need to use any AFCI's. If I had the breakers alone would have added about $600-$700 to the cost of material. That would be on top of the already added cost of several hundred dollars for the emergency disconnect and surge protection.

I do mainly custom homes in the 3-4K sq ft range. Nothing huge but usually end up with about 30 single pole circuits and 4 or so 2 pole circuits.

So AFCI and GFCI breakers add up quick.

A service upgrade? Ouch!

The electrical cost for most of the homes I do equals about 3% of the total cost.

We still have companies around here that are charging about $5 or so a sq ft for rough, finish can lights, and all material.

Can’t see how they do it for that amount.
 
Side note on required outdoor service disconnect: Instead of making homeowners spend a lot of money why don't the Ultility companies incorporate a device inside of smart meters to disconnect the power. Smart meters already have a relay contact to disconnect power. I know a relay should never be used as LOTO but sure they could engineer an insulated arm or something to mechanical lock out relay contacts. I have installed two gang ( over under ) 100 amp meter sockets where wall was barely wide enough to shoe horn in the meter sockets due to back door and garage door taking up most of the back wall. Good luck installing two disconnect switches. Not a fan of ever having circuit breakers outdoors. Life span reduced due to temperature extremes, moisture and bugs. Have a question : We we're told a few years ago that type NM cable is not legal to feed any outdoor luminare because cable is not approved for damp locations. That makes it appear that is not legal to run type NM cable to any outdoor circuit breaker panel. Does this mean you might have to install a trough indoors then run pipe nipples from that to outdoor panel when using type NM cable?
