An EICR is usually broken down into three main elements, these include a visual inspection, dead testing and live testing.
Visual inspection:
The visual inspection is pretty much as it says. We will usually start by turning off all your electrics and isolating the installation using a suitable lock off kit. This means we can inspect each element of the installation safely. This includes but is not limited to, removing sockets, light fittings and light switches so that we can inspect the state of the wiring to all the various points within your property.
Dead testing:
Providing that the visual inspection has not shown up anything of concern, we will then carry out a series of dead tests on each circuit. These dead tests are generally broken down into three separate tests for every circuit and include insulation resistance testing, polarity testing and continuity testing.
Live testing:
Once the dead tests have been carried out and again hopefully nothing untoward has been found, we will then move onto live testing. These live tests will prove functionality of basic protection such as the circuit protective conductors. We will then take readings from each socket / light fitting that is accessible. Following on from this, we will move onto testing the functionality of any additional protection including the RCD’s / RCBO’s or AFDD’s.
