Prysmian 6943X Black 3-Core 4mm² Armoured Cable 50m Drum (92129)

The correct selection of cable size will depend on what your total load adds up to, the length of run between the house and summer house and the installation method. All of these factors play a part in determining the correct cable size. If the cable were installed buried in the ground, then it could carry up to a maximum of 36A without exceeding 70°C (as will be the temperature limit for a domestic installation typically). However, you also need to consider the circuit length and the associated voltage drop for the cable concerned. We would generally advise on a maximum voltage drop of 2.5%, which would limit your cable run to about 13m. If the cable were only carrying 25A, then the cable circuit length could increase to approximately 19m.

Thank you for contacting Prysmian Group UK Technical Support. The rating of this cable will depend on the method of installation, the voltage (single phase, three phase or dc) and the circuit length (for voltage drop). The ratings are published in BS7671, Table 4E4A, although if you are connecting to 70°C rated equipment/accessories, you should refer to Table 4D4A.

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.
