Can someone please answer this for me once and for all about the emergency disconnects

[Leagle454]

Ever since the 2020 code update I have always done residentrial services upgrades as followed.

• SEU from underground or from a service drop in the meter.
• From the meter's load side SEU leaves and enters a 200Amp disconnect like these

  .
• Then it converts to SER to the panel inside the house
• All grounds from the GEC are ran to the disconnect and bonded together with the grounded neutral conductors.
• All grounds and neutrals are separated for the inside panel.

Now Ive seen that you can use SEU for the entire install so,

• SEU to meter
• SEU to disconnect
• Instead of converting to SER on the load side of the disconnect it stays as SEU
• SEU into the panel
• The disconnect can is bonded to the grounded neutral conductors with those little ground conductor that turn horizontal and connect to the ground bar.
• The panel inside get all the neutrals and grounds bonded together along with the gas and water EGCs and the GEC
• The disconnect gets labeled "EMERGENCY DISCONNECT"

What is right, wrong, why is it OK to do the later install just because you change the label to emergency disconnect instead of service disconnect?

Why is it OK to do the later install if the grounds need to be terminated at the first means of disconnect?

Does labeling the disconnect "EMERGENCY DISCONNECT" create a work around?

As long as the label says Emergency Disconnect, Not Service Equipment you can use SEU for the entire run to the panel.
