    Hob with 475mm depth cutout

    Depth to bury armoured cable in concrete with vehicles passing over?

    I will/may be burying 16mm SWA in concrete to route it to an outbuilding (for the kiln I have just been chatting about!). This will be getting driven over by cars. Is there an ideal depth for this? Also, does the SWA require any further form of protection?

    Depth of power cable?

    Unfortunately last weekend while digging up tree stumps I managed to go through the power cable for the local scout hut. SSE are now billing me £330 for fixing it! However a neighbor thought I might be able to argue it as it's only 200mm below the surface. As it was installed with the scout hut...
