An example of high rise residential block with LPS (Lightning Protection System) installed.

The specification of the CLASS I SPD will depend on the LPS installed.eg: Level I, II, III, IV

A TYPE 1 / CLASS I SPD is essential for any system that is required to comply with BS EN 62305.

We recommend a co-ordinated approach where further, down stream protection is installed to prevent damage to sensitive equipment connected to consumer units.
