Can anyone tell me what the minimum distance above the floor that a horizontal cable run can be. I'm in the middle of fitting a kitchen and I need to install extra wall outlets. What I was thinking of doing was running the 20mm conduits close to the ground(perhaps about 2" above it) so I don't have to cut slots into the sides of the carcases. The plan is to run the two 20mm conduits under the base of the carcases where the leg supports are. All I'm doing is extending the current ring and I will be fixing the conduit to the wall.Am I breaching any electrical reg regarding the height of this horizontal run, being so close to the floor.
