I would like to give this product a higher rating as it works well but mine arrived defective. The electrical contacts for "hot" and "neutral" at the end of the socket were held only by the spring tension of the contacts themselves and their friction against the top half of the clamshell. They are about 0.015 to 0.020 inches above the grounding lug, which is firmly attached to the bottom shell of the clam with a set screw. There was no insulating material between the hot or neutral contacts and the ground lug. In the absence of an insulator, there are two conditions that can cause the outlet's hot and/or neutral pin to be displaced and touch the ground lug. causes a short circuit on the AC line. The first is to use the "VOLT CHECK" ports by inserting a voltmeter probe into the port. The probe presses the contacts into the grounding lug, causing a short in the live AC line. The second reason is that the contacts can be released by tapping the bottom half of the housing near the end of the socket. This can happen if the device has ever been dropped. This in turn will cause a short circuit in the live AC line. Speaking to a manufacturer representative, I discovered that there should be an insulator between the hot and neutral terminal and the ground terminal. If you have one of these, make sure that the insulator is in yours. UPDATE: The manufacturer replaced the defective product without question. The replacement has a well-designed insulator. Upgrade to 5 stars! The probe presses the contacts into the grounding lug, causing a short in the live AC line. The second reason is that the contacts can be disengaged by gently tapping on the lower half of the housing near the end of the socket. This can happen if the device has ever been dropped. This in turn will cause a short circuit in the live AC line.
