Here we explain what each observation code means, with EICR observation code examples, so you can better understand your EICR. Fixed wire testing observation codes: C1 C2 C3 Observation Code C1. The most severe observation code, C1 means danger is present and there is an immediate threat to property or life. 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 .
