A midspan power over Ethernet ("PoE") injector (20) connects via LAM cables (514) to remote PDs (518). Each cable (514) has a remote end; and a midspan end (516). The cables (514) includes receiving and transmitting conductors, and insulated electrical conductors. The injector (20) includes pairs of sockets (24) a first socket (24) of each pair is a powered socket, and a second socket (24) is unpowered and carries only data. A data-signal bus (188) interconnects the unpowered and powered sockets. Power switches (156), equal in number to the socket pairs, connect respectively to one of the powered sockets (24). Without negotiating with a PD (518) connected by the cable (514) to the powered socket (24), a controller (34) causes switches (156) to close thereby transmitting electrical power via the powered socket (24) connected thereto and the cable (514) mated therewith to the PD (518). The controller (34) also concurrently monitors operational status: a. of each connected PD (518); and b. internal conditions within the injector (20).

An appliance's control and sensing circuit selectively applies AC electrical power to a load (72). The circuit includes a relay (44) having contacts (52) connected in series between an AC power source and the load (72). When energized, the relay's electromagnetic coil (54) changes the contacts (52) to supplying electrical power to the load (72) or conversely. The control and sensing circuit measures AC voltage induced in the coil (54) by an alternating magnetic field produced by AC electrical current supplied to the load (72) through the relay's contacts (52). A microcontroller (46) included in the control and sensing circuit: 1. measures the AC voltage produced by the coil (54); 2. compensates the measured voltage for inductive coupling between the AC current flowing through the contacts (52) and the coil (54); and 3. determines various characteristics of the AC power supplied to the load (72).
