external and internal metallic items need to be bonded to the
LPS. Separation distance requirements also apply to internal
electrical and electronic circuits; thus is especially important
to consider the existing and future use of the building. The
separation distance requirements are determined by the
lightning protection level, the position of the LPS and the
number of down-conductors. To simplify conformance to the
separation distance requirements, alternative down-conductor
location(s) and increased number may be required.
