[QUOTE="Bruspark, post: 519262, member: 20106"] It happens a lot with smoke alarms and TV aerial Amps tacked into lighting circuits in the loft etc. so once an installation is in service (as is the case with an EICR) it is usual to limit any test voltages to 250V DC or less and/or apply test voltages only between L+N and E unless a L-N fault is already evident. As this is far less than the 300v Peak from the mains its safe and if (rarely) L-N testing is tried the fact that something is connected will be quickly spotted anyway. So in short if done properly there's no damage to any forgotten appliances Footnote is that 'old but rarely switched off' appliances may take the opportunity to not restart and socket/wall switches may make poor contact when switched back on creating apparent issues after an EICR but that's not the test's fault.
