[QUOTE="Sidewinder, post: 335596, member: 9512"] I thought that there was something in the red or green about split con, but I can't find it. However, you cannot treat as swa, you have to treat as flex as it does not have an earthed outer protection anyway, as you have an insulated & sheathed live conductor wrapped around the inner core. So, you would have to protect the splitcon with a 30mA RCD. You could always go the MICC route, that would be much less obtrusive & not need an RCD, as the outer would be earthed. Going on manufacturers data 10mm sq MICC sheathed is good for 88A, less in BS7671, but you can use manuf'data, but you would have to confirm rating according to installation method, and it is less than 15mm diameter for a 2 core. If you have to go to 16mm sq it is only just over 16mm dia. Easier to hide due to size, if you got it unsheathed then it would be smaller again. Earthed outer, so no RCD required if buried also.
