From the field
What I Found — EICR finds from the field
Real faults. Real jobs. One photo, one infographic, one plain-English explanation per entry. Updated as jobs produce them.
This isn't about naming and shaming. These faults appear on installs by registered contractors, by DIYers, and on decades-old work where the regulations have simply moved on. What they all have in common: they're invisible unless you look. That's what an EICR is for.
Unidirectional RCBO — Solar PV
An RCBO that can only detect faults from the grid supply — fitted on a circuit that also generates electricity.
Separated CPC — Solar PV isolator to inverter
The earth conductor between the AC isolator and the inverter has come apart. On a live generating system, that's danger present.
Mixed-brand MCB in a split-load consumer unit
A different-brand MCB fitted into a consumer unit it wasn't designed for. The protection system hasn't been tested as a whole.
Type AC RCD — modern appliance circuits
A Type AC RCD fitted on circuits serving modern appliances. It can't detect the fault current these appliances produce.
Wondering about your own installation?
An EICR is the only way to know for certain. I price by circuit count — not bedroom count. See how it works.
