Initial verification question

[davesparks]

i did say consider. all would depend on time factor and cost .

How does time or cost change the possibility of a mistake having been made?

I was taught to test R1+R2 at the furthest point, the theory being if you test at the most furthest point on your radial circuit and get an exceptional reading it means there are no breaks in the line or cpc.
This is how I was taught.

do the guys who have done the wireing do testing as well....if not..tell them to stick their noses elsewhere

Think this video will / or should dispel any misconceptions on how to test an RFC

Measure at All points and record the highest as the circuits R1+R2, regardless if it’s not the last point such as the strappers forming the 2 way lighting to the landing light and switched both ways.

I would verify cpc continuity at all points. After all, the purpose of the test is to ensure that it is connected at all points and not just that there's a cpc path to the end of the circuit.

I would only conduct the Zs test at the end of the circuit though, having already proven continuity of the cpc.

When doing spot checks as QS I have observed that test results have been conducted at the last point of say a lighting circuit but as the permanent live in and out are at the switch then by testing only the last point of the circuit only confirms that the cpc is present at the last point.
I found that a light containing only a switch live and neutral did not have a cpc connected to the means of earthing as it had not been adequately connected at the switch point, so it’s important that it is done at all points.
This was a school job in which all lighting is metallic and as such ,exposed conductive parts.
