Historically, this function was delegated to isolation transformers, which use inductive coupling between CSA Component Acceptance Notice # 5, etc . Opto-isolator specifications published by manufacturers always follow at least one of these regulatory frameworks.

An isolated power system was furnished, from a special isolation transformer, with the intention of minimizing any leakage current that could pass through equipment directly connected to a patient ( for example, an electrocardiograph for monitoring the heart ).

A line "'isolation transformer "'for telephone use is a special type of impedance matching transformer that is used to couple telephone land lines to subscriber equipment to prevent dangerous common mode voltages from appearing on the line.

Although, personal, I think the method " sucks ";-) On a property of this age check that you have and earth leakage trip ( an ordinary circuit breaker will not do ) or an isolation transformer somewhere between the distribution board and the vac .-- talk ) 20 : 56, 19 December 2013 ( UTC)
