This Q & A is one of thousands posted in our Technical Expertise area, and answered on a daily basis by our Voltimum Experts.
Question: We have erected a palisade fence around a new external compound housing three new chilled water air conditioning chiller units.
This fence stands approximately 2m from the existing building and is 18m x 7m x 6m tall. The existing building is about 10m high and has lightning protection fitted.
Is there a requirement for lightning protection to the fence that you are aware of?
Answer: There is no requirement for the fence work at this point to be bonded and this does not come under the requirements of the current BS 7671: 2008.
However, this may need to be looked at from the requirements of BS EN 62305: Protection against Lightning.
