¹ The maximum number of pushbutton cables that can be prewired is one. It is possible to wire in more than one pushbutton but it requires paralleling the wiring to the existing cable. Contact Carmanah for further clarification.

² Terminal blocks are exposed to the end-user. Everything up to the terminal blocks is prewired by Carmanah for convenience.

³ The exposed terminal blocks are ready for a total of one pushbutton. An additional pushbutton can be doubled up on the terminal blocks using ring terminals, thus increasing the capability to a total of at least two. Stacking more than two ring terminals is not advised and should be broken out into Wago splicing connectors instead.

Contact Carmanah if adding higher power draw talking pushbuttons to ensure the added load will be sustainable for your installation.
