BS6701 calls for cables to be CPR Cca
The vast majority of cables on the market are CPR Eca. Quite a few are now available (but not as standard) to CPR Dca, far fewer are to either CPR Cca or CPR B2ca. Some cables are simply not available to anything higher than CPR Eca.
We have one of the widest ranges of Cca / B2ca cables on the market.
