Quick Wago question - push fit, release?

Question

The 13A ring main in the lounge has a join inside a Wago box to allow the ring to be split and extra power sockets added in the fireplace area.

I've just had a look inside and they are the neat little push fit clips. At first look there seems no obvious way to press something and release the clip so the joint can be un-made then made again.

Are the push fit clips single use i.e. you have to cut back and fit new clips?

I just want to move the wire where it goes over an intermediate wall and would be directly against the insulation.

If it is a cut and replace I might as well fit a temporary 13A socket instead, but it would be neater in the short term if I could reuse the connectors and the box.

Wago site shows wires being pushed in but not removed.

Cheers

Which type of Wago connector?  Sounds like the 773 series, in which case I believe you pull while  twisting back and forth, though I've never removed a cable from that  type, only from the 222 series.

Tim Watts · Answer

Yes - twist and pull.

I'd look at the removed end afterwards, and if it's been "drawn" by  pulling it out, I'd cut and strip a few extra mm off before re-inserting it.

Dave Liquorice · Answer

A free wire can be "unscrewed", just leaves a sprial mark on the copper. I'd expect to just have a zig-zag mark as the wire is withdrawn. It'd take quite a bit of force to draw a bit of 2.5 mm copper.

I wonder if these things will still be srviceable in twenty years? Or will they be starting fires? Especially the heavier current ones.

Mike Clarke · Answer

Yes, the end of the conductor removed from a Wago connector is generally in  a much better condition for re-use than one that has been tightly clamped in  a conventional screw down terminal.

I think they will probably be fine.

Remember though that when used in a location where maintenance free standard apply then the current rating for the connectors are reduced.

dennis · Answer

As they are spring loaded unlike screw in terminals they should be fine. IDC connectors work in a similar way and they are by far the most  reliable unless you are using wire wrap which is better.

There was another thread on this a month or two back. ISTR they only have a 1 year warranty when used at 32A. I would never use them on a power circuit. Ah, plastic consumer units mark II.
