SAM BAUGH: WHILST CARRYING OUT AN ELECTRICAL CONDITION REPORT IN SOUTH WALES, WE CAME ACROSS THE PICTURED IMAGE – NO NEED TO WORRY ABOUT AN ENCLOSUE ON YOUR RCBO!
Although the highlighted issue was the enclosure (or lack of!) on the RCBO, there are several other observations that would need to be documented on the EICR.
The lack of an enclosure for the RCBO would create several observation codes. This installation appears to have been subject to a new smart meter installation, where the smart metering installer has placed a see-through plastic sheet as a temporary cover over the offending RCBO.
The RCBO itself has been connected via the main switch of the left-hand consumer unit via the four-core flexible cable. Flexible cables aren’t suitable for fixed wiring unless they meet the S requirement of Regulation 521.9.1. The green and yellow conductor of the four-core flexible cable has been utilised as a neutral conductor. The reference conductor of the RCBO has been connected to the service head neutral/earth terminal which is only for use for termination of the earthing conductor.
The Solar PV installation has single insulated conductors exposed at the meter tail connection blocks where the sheath of the twin and earth cable has been removed. The use of an AC type RCD for the circuit supplying the Solar PV and the provision of a second circuit-breaker shared with the RCD supplying the Solar PV is not permitted. The cable connected to the Solar PV generation meter has the sheath removed, exposing the single insulation apparently to permit the cpc to be terminated.
The AC isolator does not meet IP requirements of Regulation 416.2.2 with two flexible cables entering the top of the isolator.
