No Neutral required? Does that mean a neutral is optional?

[Retired Steel Worker]

For many Caseta dimmers and switches Lutron uses the words "no neutral required."

Exactly what does this mean?
a. You cannot use a neutral. As in never ever, there are no neutral connections on the switch housing.
b. Using a neutral is optional. You can use a neutral if you want but it's 'not required.'
c. Something else.

They don't have a neutral connection on the switch.

Hello we use three terms with our controls:

Neutral Required = This means a neutral is required to connect to the control.
Neutral Optional = You will see this on Phase-Adaptive controls like the Maestro Pro Dimmer. This means it is an optional connection to use on the control for certain load types.
No neutral required = This control will not have a neutral to connect to at all. You could consider this the neutral-less version.

Thanks for the clarification.
