I have to provide a 160A 3P service to a building over a 65 meter run in highly reactive soil. We have been told to allow for a vertical movement in the soil of up to 300mm around the building perimeter. I am thinking of using 100mm diameter HD corrugated conduit. Will this do it or is there some other solution? I am concerned because to me 300 drop over only 65 meters seems a lot. I can allow for extra cable and loop inside the cabinet and this should protect the cable from being ripped out of its connectors but I am concerned that the conduit may tear or split. What can be done here?
Hi Peter,
Unfortunately, we can't offer advice in this instance, as there are too many variables on the site we cannot know.
