For junction boxes placed in ceilings, such as for recessed lighting or fans, a common recommendation is to mount them at least 6 inches away from the nearest wall. This provides sufficient clearance for wiring connections and promotes adequate support for fixtures. The National Electrical Code has published a chart that determines a junction box’s correct size, based on the number and size of the conductors it must accommodate. The size of a conductor is expressed as AWG (American Wire Gauge); the . Surface-mounted electrical boxes for all electrical fixtures must be raintight/weatherproof. Exterior light fixtures do not require GFCI protection. Low-voltage lighting systems must be listed by an approved testing agency as an entire system or assembled from individual components that are listed. Standard North American junction boxes come in a variety of shapes and sizes (round, octagon, square, rectangular); however, most wiring devices intended for junction box mounting, save for light fixtures, are designed around the standard device yoke mounting pattern -- this is defined in NEMA WD-6 (an abridged version can be found here) as a 4 .

RFID blocking wallets and bags that claim to block RFID signals typically use what is called a Faraday cage, named after scientist Michael Faraday. Faraday cages are essentially metal cages that shield their contents by taking the electromagnetic radiation and distributing it around the exterior of the cage, instead of allowing it to penetrate.
