NOTE:
A larger breaker may be used even though in theory it may appear that the 2.5mm
it is protected on two accounts. Firstly it is protected by the rectifier input fuse (which is only a short distance away). Secondly,
the rectifiers are power‐limited on their input. Therefore, they can never be overloaded. As a result, the wire can never be
over‐loaded by the rectifier – it can only see fault current. As a result, depending on local authorities, only fault current
protection may be catered for by the upstream protective device.
