Wago connectors in a ring main

[Bul]

Some Wago connectors are rated at 24 amps and take cable up to 2.5mm. Would you use them on a ring main circuit?
My concern is that if one leg of the ring went open circuit, the wago would be then used on a radial circuit protected by a 32a mcb.

and a 2.5mm cable (look up cable rating)....No problem using 24 amp wagos on the leg of a ring.

Considering that 2.5mm cable is also rated at 24A (before any correction factors), yes.

Your concern is justified, and that is the reason why I never use ring final circuits, I always wire in radials on 20A breakers.

The point is that if the ring circuit becomes a radial circuit the 24 amp rated wago would be on a 32 amp circuit.

2.5mm cable is rated at 27amps before any correction factors. Nothing wrong with ring finals or 24 amp wagos on a ring, ok if it goes "open circuit" then the circuit has been damaged, the same way a radial circuit might be damaged and loose its cpc.

The point is that if the ring circuit becomes a radial circuit the 24 amp rated wago would be on a 32 amp circuit.

and so would the 2.5mm cable. If your talking about altering a ring into a 2.5mm radial then you would have to change MCB to 20amp and 24amp wagos would be ok

The 2.5mm cable is also rated at 24A. If the ring became a radial, the 24A cable will also only be protected by a 32A breaker. There is no issue with you using the wagos.

Edit: Jonny66 beat me to it

2.5 is rated at 30A.

On tray in free air!!

Great news! Lets all wire our rings on tray and in free air from now on! I quite like the 'industrial look', I reckon it will go well in the living room! I don't think it will take much persuasion to get my customers thinking the same way

I know some steam punk type people who would love that look in their houses, cheaper than MICC... :lol:

 

[SPARTYKUS]

I guess if you could guarantee a very low temp permanently as well (but still within the limits of the cables operating range....) you might just squeeze it up to 32.....

 

[Jonny66]

Or you could bring it back round on itself forming the shape of a ring and.....

The lever type wago's are rated at 32amp, its the push fits that only take twenty odd.

Grid switches too

This has been disucces at length in other posts. It is possible for 32A (definitely more than 24A) to pass through a connector under normal use.
LINE recommend our 32A push in range (or as suggested the 32A levers).

Wago make a 40 amp rated push fit connector, it has three terminations in it takes up to 4mm and is red, cannot remember the partnumber though.

773-173 is the part number of the red 41A wagons.
