When a dp switch such as this (http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=A331832&ts=13540&id=53010) is being used in a dedicated enclosure as an isolator between metre and CU does it matter if the incoming tails from the metre go into the top or bottom of the enclosure or is it good practice to have the supply going into the top and the load coming out of the bottom?
Also, can a CU be fitted directly to a plastered wall?
