Neicy, are you translating this? Because if that is not a translation error, and a surveyor in the US actually wrote that, I would suggest he needs to be keelhauled.
Lightning grounds never are fused. They never need fusing. The nature of lightning is that you want the entire strike to always go to ground, and the ground bus itself will literally blow away (like a fuse) if the strike is excessive. There are no fuses on the consumer market that are designed to take megavolt megawatt service, which is what your lightning ground is designed for.
If, as it suggests, someone actually CHARGED you for replacing such a fuse? Then they should be keelhauled twice, and turned over to the local authorities for fraud.
Just remember, at least here in the US, you need an EPA permit before you can conduct a keelhauling.
