The four main EICR codes are, Code 1 (C1), Code 2 (C2), Code 3 (C3) and Further Investigation (FI).
C1 = Danger present
A code 1 observation must be rectified and made safe without delay.
An example of a C1 observation (it’s dangerous now!) would be the cover of a consumer unit missing hence exposing live parts. Any exposed live parts such as an open consumer unit busbar or an exposed live cable end would be classed as a code 1, as it is dangerous (right now) at the time of the inspection.
C2 = Potentially dangerous
A code 2 observation must be rectified as a matter of urgency.
An example of a C2 observation (potentially dangerous) would be no RCD protection to an external 13A socket. A C2 potentially dangerous observation extends to any potential dangers, hazards or risks which could occur under certain conditions or under fault conditions such as, this could become dangerous should that happen.
C3 = Improvement recommended
A C3 observation is a recommendation for improvement.
A code 3 would be an observation you feel warrants a mention on the report of something you feel should be improved but would not be classed as a C1, C2 or FI.
FI = Further investigation required
An FI observation must be investigated as a matter of urgency.
Further investigation would be allocated to an observation which could be potentially dangerous but could not be determined at the time of the inspection, therefore requires further investigation into the defect to be able to determine what code to allocate against it.
LIM = Limitation (not tested or inspected)
An inspection report schedule of items inspected may include “LIM”, meaning a limitation has been applied to the inspection.
A limitation (LIM) noted on a condition report means that a particular item(s) and / or circuit(s) have not been tested or inspected. This could be due to no access to a particular area of the installation such as a server room, therefore the circuit supplying the server room could not be tested or inspected hence a limitation has been applied.
A limitation could also be a pre-agreed limitation agreed with the client, i.e. the client does not want you to test or inspect that specific area or item.
Another example of a limitation could include high level warehouse lighting, if there is no safe working access to the high level lighting then a limitation might be applied.
NOTE = A noteworthy comment
An item the inspector has deemed noteworthy but not necessarily related to electrical safety, a “NOTE” has no bearing on the outcome of an inspection.
