R1 R2 on Radial circuit

[TheCodboy]

Just installed a small length radial circuit. Total length from board no more than 2 meters. Halfway along is a FCU and a double socket at the end. Linked line and earth and tested at the socket and got a R1 R2 reading of 0.10 ohms,hit the switches to confirm polarity and the reading stays the same. Am i missing something here? surely i should loose continuity and the meter should go full scale, just like when testing R1 R2 on a lighting circuit? Am i having a proper brain freeze moment here??

wwhat is the point of putting test leads on terminals at back of socket and turning socket switches on and o

exactly my point

Yes..... see where your coming from now.

exactly my point

The OP may have realised his error, if we are correct, which seems likely, but there is no shame in making a mistake we all do it, it's how we learn, I hope he comes back and puts our minds at rest, certainly not going to take the proverbial out of him.

I'll correct myself unless you are checking operational of the socket

I was using the plug in tester and was getting silly high readings even after nulling, hence why i dropped the socket front and tested at the screws. Of course i wont get any break in continuity testing at the back..... As Cpt Mainwaring used to say..... Time to get a new plug in adaptor i think.

Good man

Is it a metrel tester?

 

[TheCodboy]

Can i just ask one more thing? Why do you guys not like the idea of a double socket fed from the fcu? The garage door from the fcu is only a 50w motor.

From what you've described the 2G socket isn't fed from the FCU, they are both in series on the radial.

Have you taken the supply to the socket from the load side of the FCU? The ideal way of doing you circuit, would be feed from CU to socket, FCU to feed door motor suitably fused down,not the way you have configured it.

Sorry yes,its not fed from the fcu. Im just having a bad day....

I think its fair to say ive made a rather silly mistake..

Jesus reading that full thread confused the crap out of me!

testing at the screws

At a guess the terminals
