A test socket (14) for a testing an integrated circuit (12) with controlled impedance while maintaining the structural integrity of the test pins (20). The pin (20) can have a sidewall with a thick portion 32 and a thinner portion (30) along the length of the pin. The pin can have projections (42) which provide a standoff from the slot (40). Treat grounding seriously. This is a "canary in the coal mine". And what its warning you to do is do a serious evaluation of the Grounding Electrode System for each of the buildings. However I would advise only a cursory inspection - that the Grounding Electrodes are present and intact, and that the main panel has an intact neutral-ground bond - until you have evaluated .
Testing electrical panel covers to see if energized
Short answer - yes, but you could ground it in a more reliable way. A lot of those older metal boxes I run into have the ground wire wrapped around a screw on the outside of the box. The tester says they're grounded, which is correct, but like what the hell 1980's electricians?
