Electrical safety testing that all connections are sound. Live testing Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified RCD testing: on modern electrical systems RCD’s and RCBO’s are regularly fitted, these devices react to electricity missing from the circuit or installation such as when a person is receiving an electric shock as the electricity passes through his body to the ground (earth). The competent person will then issue an Electrical Installation Condition Report (EICR) also known as Periodic
Infraspecific name is "Acanthocalycium klimpelianum", which can be abbreviated to "A. klimpelianum" where the context makes the genus clear. The species cannot be referred to as just "klimpelianum". In the same way, the name of a particular variety of "Acanthocalycium klimpelianum" is "Acanthocalycium klimpelianum" var. "macranthum", which can be abbreviated to "A. k." var. "macranthum" where the context makes the species clear. The variety cannot be referred to as just "macranthum". Sometimes more than three parts will be given; strictly speaking, this is not a name, but a classification. The ICN gives the example of "Saxifraga aizoon" var. "aizoon" subvar. "brevifolia" f.
