6mm Twin & Earth Surfix Surface Cable is a heavy-duty PVC-sheathed
electrical cable designed for high-load circuits in South African
residential and commercial installations — most commonly used for
geyser circuits, stove circuits and large air conditioner sub-circuits
where 2.5mm cable is insufficient.
Constructed with a plain copper conductor, PVC insulated cores laid
up with a bare tinned earth wire in contact with a longitudinal
aluminium foil tape, and PVC sheathed overall — this cable is SANS
1507 compliant and meets all South African wiring code requirements
under SANS 10142.
Sold in standard 100m rolls, the 6mm 2+E Surfix cable is protected
by a 40A circuit breaker and is the correct cable size for geyser
and stove circuits in South African homes and commercial properties.
