Abstract
An electrical plug for testing an electrical mains socket is provided. The plug comprises a pin for engagement with a pin receptor of the mains socket. The pin comprises first and second electrical contacts, each comprising a surface portion to engage with a different respective region of the receptor. The first and second contacts are electrically isolated from one another at the pin. An electrical testing system and a method of testing an electrical mains socket is provided. The testing system comprises the electrical plug and a first circuit connected to the contacts and configured to measure an electrical resistance therebetween. The method includes providing the electrical plug and measuring an electrical resistance between the electrical contacts. A further method is provided for testing an electrical mains plug comprising a pin, by providing an electrical socket with a pin receptor having first and second regions electrically isolated from one another.
