Yes. Visual inspection is a very large part of an EICR, as huge numbers of problems would never be found by testing.I am assuming a visual inspection is the only real way to find an indication of a loose connection?
All of these would be usual things on an EICR, and any one of them would have identified the damaged switches/FCUs.
- checking that switches operate as intended
- that fuses in FCUs and other places are the correct value
- removing at least some of the switches/sockets/others to inspect the terminations/wiring
