Hi All,
We are currently liaising with a Client regarding a project where they have not been with the D&B contractor in terms of quality of the installation, and ultimately the electrical design. The Client is asking for us via a new D&B Contractor to review the design and current installation to see what can / cannot be utilised going forward.
One of the items of concern that stands out immediately is the original design is the use of a 5 core SWA cable to supply 2 No. EV charging points. With both charging points being single phase on separate ways within the distribution board. Way L1 using cores 1+2, with way L2 using cores 3+4 we have not yet opened up the EV Charge points to see if core 5 is spare with the SWA being a common CPC, or whether core 5 is used as common CPC.
We have concerns regarding the use of a cable with multiple single phase circuits within it, and the use of a common CPC for both circuits, is this allowable with in the regulations?
