Dunc Posted July 19 Share Posted July 19 My build will have an attached garage. If I put the consumer unit in the garage can all of the electrical cables from it be fed through a single duct through the insulated house wall (300mm cellulose fill) and then sealed? Perhaps using one of those mulit-cable conduit seals such as https://www.filoform.co.uk/filoseal-hd-re-enterable-duct-sealing. Or am I better to find space to put the CU inside the thermal envelope?

Use a hockey stick tube and then easy to seal at floor level. Then take power to the garage with a single cable to a dedicated CU for the garage. 1 1 Link to comment Share on other sites More sharing options...
