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.

Would I need the neutral for a maestro MA-PRO 3 way powering LED lamps?

[Joy L.]

Hello jknsd, welcome to the Forums. The MA-PRO is a neutral-optional device when used with standard 120V LED lamps that do not require a magnetic low voltage (MLV) or electronic low voltage (ELV) dimming signal. From our spec sheet, in regards to using the MA-PRO with standard LEDs, we state that "Neutral is recommended for best dimming performance, if available, but is not required for this load type."
