Any opinions as to which is best?
I have tried both, and I think the Ideal connector levers are more secure than those on the small Wago 221 version.
On the new small Wago 221 connectors, I have found the levers tend to lift easily.
I have read somewhere, (but I can't locate the source), that because the RCBO's electronic control operates at a very slightly higher potential than earth, there is a very small leakage to earth through the functional earth lead.
Is this correct or is my memory playing tricks?
I am looking at buying an earth leakage clamp meter AMECaL ST-9810 (£59) or a Megger DCM305E (on offer at £194).
The only use will be mainly domestic fault finding.
Any opinions will be most welcome.
Is there any requirement or logic to using fire-retardant cable cleats for SWA inside a wooden shed?
There will be a 2 metre vertical run and a 3 metre horizontal run of 4mm 3 core SWA.
Is it acceptable, using a two-wire RCBO tester, to test at a light switch using the phase and earth wires?
If it is acceptable are there any disadvantages?
