UL 508A Section 66.1.5 Clarafication

[BurtP]

Clarification on what disconnects fall into this requirement?
AB 194R w/o Defeater ?

I'm not sure which Allen Bradley disconnect your speaking of but you can have a service defeat mechanism as long as it has self restoring mechanism. Most disconnect devices should meet the requirements of IEC 947-3 for disconnect devices.

By "self restoring" means that when you close the door it must be reset or the door will not close. Christopher Caserta
