Questions $21$ to $26$ relate to the following scenario.

An earth fault loop impedance test is to be carried out on a $32$ A radial cooker circuit as part of an initial verification of a sandwich bar.

The $22$ m circuit is wired in $6m\frac{m^2}{2\mathrm{.}5}m{m}^2$ flat profile PVC cable. The circuit is protected by a BS EN $6089832$ A Type B circuit breaker.

The installation has an external earth fault loop impedance of $0\mathrm{.}17$

What is the expected measured earth fault loop impedance value for this circuit?

a $$

$0\mathrm{.}23$

b $$

$0\mathrm{.}40$
