    en.wikipedia.org/wiki/Ring_circuit

    Spur circuits attached to the ring can overheat if not fused at the spur-point (i.e., if a BS 5733 or similar fused spur is not used) This is almost certainly a breach of the appropriate electrical standards (e.g. BS 7671 in the UK): the maximum load on any unfused spur is a single fitting.

    SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...

    en.wikipedia.org/wiki/AC_power_plugs_and_sockets:...

    In this arrangement a cable connected to a fuse, or circuit breaker, in the distribution board was wired in sequence to a number of sockets before being terminated back at the distribution board, thus forming a final ring circuit. In the final ring circuit, each socket-outlet was supplied with current by conductors on both sides of the 'loop.'
