How come, always thought the links had to be fitted to make star or delta for the...
Hi guys,
Been getting a bit of practice with my new Metrel MI3000.
Most functions are fine, but I'm a little confused by the Z Loop impedance test.
In the book, it shows the Line, Neutral and PE probes being connected to their respective terminals on the board.
When I do this and press test...

Do RCBOs normally have 2 flying leads - neutral and earth?
Are there "old" rcbos and new types.
The reason I ask is that I have bought Proteus RCBOs and they have a flying neutral wire only.
I've never fitted RCBOs before and am just a bit confused.
Any explanations appreciated.

Hi,
An electrical cooker stays on for a while and trips the RCD. When the RCD switched back on straight away, the cooker stays on for a length of time and trips again (doesn't trip straight away). The circuit tests OK and the MCB stays on all the time.
What could be issue and where...
Looked at a job today on a TNS installation where the customer wanted a shower replacing. The gas and water supplier did not have any Main Protective bonding attached. The Main Earthing Terminal only had a single connection point to which the Earthing conductor was attached and then attached to...

I recently telephoned our DNO & asked if the property I'm working on is in a PME area.
