100 amp service upgrade

[Sparkey1981]

Hi haven’t taken my 2020 code class yet end of March was first one I could get into.
In the mean while I have a 100 amp residential service upgrade to do in Massachusetts.
Other then emergency disconnect out side. Which I plan on using a 100 amp main breaker meter socket and labeling it emergency disco and service disco
As I will run SER into the panel.
also plan on afci/gfci the panel plug.
Any other 2020 changes that I need to be aware of for service upgrades
Thanks

You are required to provide a surge-protective device. (230.67)

Also, if there is an existing 3 wire range or dryer receptacle fed with SE cable, you would create a violation to 250.140. There are ways to deal with this without having to run a new branch circuit.

Thanks I did read about the surge protector
How do you deal with the 3 wire dryer or range ? Thanks

Could I run SEU mark the meter not service equipment and label panel service disco?

Exactly

They are now 4 wire. Hope they aren't too far away.

Why couldn’t I do as I mentioned above ?
Running new dryer and ranges circuits for a service change and changing cords for the appliance seems out of control for a service. Upgrade

Your label of Service Disconnect is now under the Meter, feeder to the panel will now need to be 4 wire, which changes your dryer and range to 4 wire.

Leave it as Emergency Disconnect only and you are not required to change to 4 wire. My interpretation. Others may disagree. The indoor panel will need to be Service Equipment with MB, etc.

I agree with that I also spoke to a local inspector who had the same interpretation.
He did mention that Milbank is coming out with a meter socket with a built-in disconnect
Thanks

How far are you entering the structure before hitting the service disconnect? That is first thing that will determine if this is even an option

(A) Lot of discussion on equipment that is Listed as "Suitable ONLY For Use as Service Equipment" being labeled "NOT SERVICE EQUIPMENT"...

(B) There is equipment Listed SUSE or "Suitable For Use As Service Equipment"" that can be used as service equipment or as just a disconnect.

Would not (A) be a violation of 110.3(B) in that the equipment is being used against its listing...

And (B) would be using equipment within its listing.

Directly behind meter no issue with that.
I have done 100 service changes and this would have been cut and dry with 2017 code
It still isn’t terrible I just want to get it right the first time

"Suitable only for use as service equipment" items have the grounded conductor terminations permanently connected to the frame of the item, you can't just remove a bonding screw to float the grounded conductor. Nothing wrong with using such items before the service disconnecting means because you must bond items ahead of service disconnect to the grounded conductor anyway. Only way you can use such an item after service disconnect is if you are landing an EGC on the grounded conductor terminal(s) and not a current carrying grounded conductor. See this with pump panels a lot, they are usually suitable only for use as service equipment, but they almost always are used on something that doesn't even utilize a grounded conductor.
