The ECSS-101 surge protection device is designed to be installed directly from from a spare way in the consumer unit using 6mm cable. Short circuit protection should be provided by a 32A ‘C’ curve MCB.
The combined length of the connecting conductors in relation to the current path should ideally be less than 0.5 Metres and in no circumstances exceed 1 Metre.
Live + CPC = <0.5M (Maximum 1M)
Neutral = CPC = <0.5M (Maximum 1M)
