An RFID system consists of three components: an antenna and transceiver (often combined into one reader) and a transponder (the tag). The antenna uses radio frequency waves to transmit a signal that activates the transponder. When activated, the tag transmits data back to the antenna.

Where the ground rod is located far from the main electrical panel, thicker No. 3 wire may be required. In areas where codes require two ground rods because of high electrical resistance in the soil, the rods must be spaced at least 6 feet apart and interconnected by a buried jumper wire. NEC Article 250 does not specify a distance from a house to a ground rod. But the 8-foot rod should be driven into the ground far enough from the house that it will not contact the underground concrete footing of the house, which protrudes horizontally about 1 foot from the base of the foundation.
