Again ignorance of what must be done all over the world so that equipment will work in regions with better safety standards. For example, everything on a circuit (ie some 20 devices operate on one 5 milliamps RCD) without tripping it. Because that is found in North American venues and therefore in major facilities throughout the world. No problem since electrical equipment must leak typically less than 100 microamps. Even construction sites must have many equipment on one 5 milliamp GFCI without tripping. Any equipment that leaks 3.5 ma would cause consternation on job sites. Same 'less than 5 millampss' applies to secure facilities all over the world because that equipment is also used in and must also operate on North American's much safer GFCI standards.
Return to the point; to what is relevant. A tripping 100 mA RCD means a serious human safety issue. Move on to what the OP must do to have human safety.
You are arguing nonsense using standards that are considered insufficient in many venues and for human safety. Relevant numbers for human safety were for faults of less than one second. 30 milliamp protection is too high for what are normally one circuit powering 20 appliances. Everything you have posted demonstrates only local knowledge; insufficient for international design requirements. And is irrelevant to the OP's problem.
Apparently you want to argue safety standards that are inferior to what is found elsewhere; rather than address the purpose of this thread. A useful engineer would address reasons for RCD tripping either due to appliance failure, interior wiring faults, or a combination of both. And yes, we have seen where an RCD would only trip due to a combination of both - which can make solutions challenging. Nuisance tripping happens in venues with safe wiring when appliances leak an excessive 3.5 mA. But that is not the OP's problem. OP has a much worse fault that exceeds what is required for human safety. Move on to what is relevant here.
