Hi , it probably doesn't .!!!
cable in use RED,YEL, BLU, & BLK is 3 phase & N cable so if being used in domestic situation then any combination possible. need to look at supply end to see how connected, usually red L, yel, sleeved grn/yel E & blk N, blue not connected, but as out of doors then needs 'part-p ' leckie to connect or high fee to bldg control to DIY legally, regards SPARX
