My instinct here will be to replace the MCB With a Rcbo, tell the Client a FI will be required,& appropriate tests to be made on that circuit.
At least for now an Earth fault will be protected by the Rcbo…..which will be better than it is now.
My attachment above states that reasoning too.
I cannot quite understand why a few of you disagree with that option…& I fully understand the short circuit requirements…& that is typically of the high Zs reading on circuits where the Zs are high.
My concerns will also be directed @ the Company I work for…
