To help with your request, we recommend using our CableApp. The professional application used for selecting the right cable for your needs. Please visit https://uk.prysmiangroup.com/cableapp for more information or search ‘CableApp’ in the App Store or Google Play. Based on a 2.5% volt drop limit, and assuming you have a single phase, 230V system you could load 16A. Higher currents could be achieved, depending on your volt drop limit.

Please be advised that Prysmian has been unaware of a technical issue in accessing enquiries logged through Screwfix. We trust that your question has been resolved in the meantime and would like to assure you that future enquiries will be visible to us and responded to accordingly.

The current Carrying Capacities are taken from the following publications: 49A clipped direct - from BS7671 table 4E4A; 65A direct buried - from ERA, "Current Rating Standards 69-30 Part V", ERA report 89-0025. The latter publication uses a depth of 0.5m, thermal resistivity of soil 1.2 K.m/W, ground temp of 15°C, max conductor temp of 90°C. The ERA publication was based on research carried out at the behest of the UK cable industry to understand how the UK environment would affect cable selection. This publication is available direct from ERA who are part of the Edif group.

Thank you for contacting Prysmian Group UK Technical Support. We are not able to advise on accessories that may be available from Screwfix, however, the type of gland we would advise from our range of accessories would be: KA419-52 "CW 20s"
