Would this cable be ok for running from consumer unit in the house 40amp mcb run it to shed consumer unit rated at 40 amps thers 2 outside lamps and 7 double sockets that won't all be used at the same time tia
No, the 40A MCB is in excess of the current carrying capacity of the cable, you need to seek the advice of an electrician, he/she (with you) should be able to determine your actual load requirements, select the appropriate circuit protective device, use the actual method of cable installation to determine current carrying capacity (taking into account the mixing of XLPE and PVC circuits in the consumer unit), select the appropriate cable size and ensure that the circuit volt drop complies with BS7671.
