Lock OFF:
Provision to padlock the operating handle in the OFF position is standard on all General Duty safety switches.
Lock ON:
No provisions are available, either factory or field modified, on Series E or prior design series. Provision to padlock the handle in the ON position is provided on Series F devices (field modification required), (subject to local code regulations - consult local authorities for interpretation). On Series F devices, the lockplate on the side of the switch next to the handle has a very small indentation (a center punch) towards the top of the lockplate, which may be drilled out to accommodate a padlock. Note that drilling a hole in the steel of our painted devices will expose unpainted steel, which should be touched up with paint. Our gray paint is in a spray paint can, catalog number PK49SP. Consult the latest Square D Digest to determine if a specific catalog number is being manufactured in the Series F design.
