A case for enclosing an electric device, such as a personal voltage detector is provided. Embodiments of the case can increase safety and convenience to wearers operating near high-voltage electric lines, and combine (i) the ability to wear the case in either an open or closed position around a user's neck, (ii) the ability to adjust the position of the case, when either open or closed, to an appropriate mid-chest or mid-torso position, (iii) the ability to use the device when the case is open and worn around a user's neck and the device is inside the case, and (iv) an electrically shielded enclosure. When closed, the case can disable the electric device, allowing the device to be always on.

The wearable case of claim 2, wherein the electrical device is disposed on the first portion. 4. The wearable case of claim 2, wherein the electrical device is a voltage detector. 5. The wearable case of claim 1, wherein when the wearable case is hung around a wearer's neck, the first portion rotates downwardly when rotating from the closed position to the open position. 6. The wearable case of claim 5, wherein the first portion rotates approximately 180 degrees to the open position. 7. The wearable case of claim 1, wherein the adjustable member is attached to the second portion. 8. The wearable case of claim 1 further comprising: a releasable closure located between at least a portion of the first portion and at least a portion of the second portion, the releasable closure operable to join the first portion to the second portion in the closed position and operable to separate the first portion from the second portion in the open position; andwherein the first portion rotates approximately 180 degrees to the open position. 9. The wearable case of claim 1, wherein the first portion can move relative to the second portion to expose the electrical device in the open position. 10. The wearable case of claim 1 wherein the mounting structure comprises a strap. 11. The wearable case of claim 1 wherein the mounting structure comprises a mounting hanger. 12. The wearable case of claim 1, wherein the layer of electrical shielding material comprises a polyester rip-stop plane weave having a surface resistance of about 0.05 Ohms. 13. The wearable case of claim 1, wherein the external layer and the layer of electrical shielding material comprise different materials. 14.
