Do modern main board earth blocks - that accept 16mm² and 10mm² earth cable use 'shear screws' - to ensure cable clamping screws are not overtightened.
If they are shear screws, how do you then check the cables are clamped tightly at a later inspection.
... or has my electrical wholesaler sold me a duff and told me a porkie.
Thanks.
