Whatever design wins should also be available as a standalone device (maybe even something that can be installed inside an existing enclosure if there’s room and maybe even in a circuit breaker format) and not just a meter ring adapter. There are users who, for various reasons, cannot use meter ring adapters as switches. For example:

- Some services cannot be switched at the meter ring. This includes services that use a current transformer separate from the meter. (As far as I know, this includes all services over “Class 320”.)

- Some apartments aren’t separately metered. Fortunately, this is rare.

- Some users will want to back up only part of a service.
