This document discusses, among other things, a self-test ground fault circuit interrupter monitor configured to generate a simulated ground fault starting in a first half-cycle of a first cycle of AC power and extending into a second half-cycle of the first cycle of AC power, wherein the first half-cycle of the first cycle of AC power precedes the second half-cycle of the first cycle of AC power. This can be achieved by, for example, embedding in a paper or film-form medium a thin semiconductor chip up to 0. A second connecting strip portion connects the second and third strip portions. The service database is modified to remove selected service data that is absent from the selected billing data. The rear core is substantially contained within the boat-tail. The float sections are connected to the back side of the fastener component only at their ends, and otherwise lie against the back side of the fastener component to reinforce the resin base against tearing.
