An electrical adaptor comprising a housing. A male electrical plug comprises a prong extending from the housing and is configured as a standard 120-volt male plug. The prong comprises a distal tip, and the distal tip forms an end to the male electrical plug. A female socket is electrically connected to the male electrical plug and comprises an electrical contact positioned in the housing. The female socket is configured to receive a standard 120-volt male plug. The electrical contact comprises a distal tip, and the distal tip forms an end to the female socket. At least one thermal indicator circuit is electrically connected to the male electrical plug and the female socket and is electrically positioned between an end of the male plug and an end of the female socket. The thermal indicator circuit is configured to actuate an alarm upon detecting a temperature at or above a threshold temperature without interrupting electrical flow between the male electrical plug and the female socket.
