Maintenance free cable connector

When fitted in the correct box

The following Wago range is maintenance free and there are also wago boxes to put the connectors into.

Really helpful, thanks.

Can't seem to find MF kits of inline 221 connectors/carriers/boxes, so works out quite expensive, but hey . . .

Many thanks - that last one (Ashley J804) looks neat/easy.

The ability to use Wago’s in a maintenance free situation is clearly outlined on the leaflet that comes with a Wago box.

Depending on current and maximum aggregate current the 773 series of push fit connectors should be used. So for instance a ring main with a 32A breaker would require 773-173 connectors and the Wago box lid secured a cable tie in the locking point.

OK thanks. Couldn't see a pdf of the leaflet on the web site, which seemed odd. What's there just seems to allude to maintenance free without actually using those words.

Yep - the videos posted elsewhere in this thread give a good overview.

Below are links to the documentation that came with my Wago boxes and the Wago Box XLR has similar information about MF.

The 773 series seems to have been replaced with the 2773 series and the information has changed slightly. The 773 series is still available or was until recently from electrical wholesalers, I got mine from CEF who if you did not want an entire box of 100 do sell boxes of 5.

That's good of you, thanks. In the end I got a box of 221 inline connectors (seemed a lot neater to me) and Light Wagoboxes* - and yes, they came with leaflets!

Although why they (don't appear to be) online I've no idea.

The Wago connectors, when used in a Wago box, and with some limits on the total current of all conductors running through the box, can be maintenance free. I believe that technically the older boxes didn't have the "MF" code stamped into them, but I wouldn't let that bother me if I had old stock left to use up ...
