"It is not permissible  to introduce an external connection for the purpose of intentionally creating a residual current to trip an RCD."


What problems, hazard or danger will ignoring this regulation create?

    A fusible resistor is OK, like class X caps there are very specific resistor designs that are assured to fail to OC when overloaded or overheated. The do cost a few pence more than the ones that make good ignitors for fireworks.

    I also thing the intention when the reg was introduced was to head off  the 'naughty Estop' designs with a short between N and E.
