SWA supply burial depths

[danny124]

Ok here's one, been flicking through all the books. And found some answers in an unlikely source....ready..... haha the B&Q DIY book a friend had haha

SWA supplying my grandads shed/workshop.... SWA to be buried under the lawn and patio...

Depth for cable under lawn says 750mm but the BS7671 800mm

But nothing for the Patio depths is this the same or can i trust the unlikely source of the B&Q book which states 450mm depth under patio's...


Is this right, or can someone give me a page number in the regs, i can't find it anywhere


cheers guys


kind regards

Danny

500- 600mm look in the Electricians guide to build regs not sure what page its not with me at mo.
buried cables should be marked with suitable tape.
