Abstract
An enclosed switch, a bus plug or a panelboard switch with means to lock them in an OFF position are provided. An enclosed switch comprises an operating handle with a first hole situated at a distal end and an enclosure including a cover. The operating handle is disposed external to the enclosure. The cover having a flange including a tab formed with a second hole that is configured to be aligned with the first hole of the operating handle in order to lock the enclosed switch in an OFF position without the use of a handle guard.
Claims14
An enclosed switch having a first side and a second side, comprising:
- an operating handle with a first hole situated at a distal end, wherein the operating handle is installed pivotally on the second side of the enclosed switch;
- and
- an enclosure including a cover,
- wherein the operating handle is disposed external to the enclosure, and
- wherein the cover having a flange including a tab formed with a second hole that is configured to be aligned with the first hole of the operating handle in order to lock the enclosed switch in an OFF position without the use of a handle guard,
- wherein the cover having a top surface such that the tab is formed extending away from the top surface so that the second hole is placed above the top surface,
- wherein the tab is formed by bending a portion of the flange where the flange having a longer length than a non-bent portion of the flange,
- wherein the tab is extending opposite the non-bent portion of the flange in a same plane in which the non-bent portion of the flange is extending, wherein the same plane is substantially parallel to the second side of the enclosed switch.
A bus plug or a panelboard switch having a first side and a second side, comprising:
- an operating handle with a first hole situated at a distal end, wherein the operating handle is installed pivotally on the second side of the bus plug or the panelboard;
- and
- an enclosure including a cover,
- wherein the operating handle is disposed external to the enclosure, and
- wherein the cover having a flange including a tab formed with a second hole that is configured to be aligned with the first hole of the operating handle in order to lock the bus plug or the panelboard in an OFF position without the use of a handle guard,
- wherein the cover having a top surface such that the tab is formed extending away from the top surface so that the second hole is placed above the top surface,
- wherein the tab is formed by bending a portion of the flange where the flange having a longer length than a non-bent portion of the flange,
- wherein the tab is extending opposite the non-bent portion of the flange in a same plane in which the non-bent portion of the flange is extending, wherein the same plane is substantially parallel to the second side of the bus plug or the panelboard.
A method of locking an enclosed switch having a first side and a second side, the method comprising:
- providing an operating handle with a first hole situated at a distal end, wherein the operating handle is installed pivotally on the second side of the enclosed switch;
- and
- providing an enclosure including a cover,
- wherein the operating handle is disposed external to the enclosure, and
- wherein the cover having a flange including a tab formed with a second hole that is configured to be aligned with the first hole of the operating handle in order to lock the enclosed switch in an OFF position without the use of a handle guard,
- wherein the cover having a top surface such that the tab is formed extending away from the top surface so that the second hole is placed above the top surface,
- wherein the tab is formed by bending a portion of the flange where the flange having a longer length than a non-bent portion of the flange,
- wherein the tab is extending opposite the non-bent portion of the flange in a same plane in which the non-bent portion of the flange is extending, wherein the same plane is substantially parallel to the second side of the enclosed switch.
