Collin,
If you are getting a belt just touching the CDP buttons, then you may have lost an earthing connection somewhere between the plug board outlet and the main earth.
Disconnect all the equipment from the plug board and check for any voltage between the earth pins and a known good earth. A water pipe can be regarded as a good earth reference, however the caveat here is that water pipes are now often made from plastics. You will need to determine this for your self.
