1. Scope
Below testing requirements cover manually and mechanicallly operable special-use switches:
- The parameters are for use on direct current as well as on alternating current or on alternating current only.
- For the load ratings, do not exceed 60A 250V or a lower potential (≤60A 250A) nor 30A or 2HP at 600V or a lower potential (≤30A 600V, or ≤2HP 600V).
2. Electrical Ratings
| No. | Item | Requirements |
