E-STOP BUTTON / BLADED LOCKABLE DISCONNECT

The bladed lockable disconnects and E-stop buttons (Table 1. Bladed Lockable Disconnect and Table 2. E-Stop Button, respectively) are examples of switches you can use for the emergency stop. You can use other switches if they have the same or similar specifications.

We list two sets of emergency switches (bladed lockable disconnect and E-stop buttons) but your system will need only one for it to work.

Switches that you select should fulfill the system requirements as well as the requirements set by the local authority having jurisdiction and by the electrical power company.

NOTE
Contact the local authority having jurisdiction AND the electrical power company for their requirements on the emergency switch. Each entity will have its own set of requirements for the E-stop button, bladed lockable disconnect, or other. Some electrical power companies require the emergency switch to be bladed and lockable.
