SWA fixing

[oxford_30]

Hopefully for the last time!!!

I have proper glandes for my swa cable, 20's. However this fitting isn't big enough for my hole in my junction box or consumer unit, is it okay just to step upto the 25's gland or is there a special gland I need to buy.
I need an answer as local electrical places just say "don't know"
Please HELP I need to finish the job!!!

Thanks

You can buy 25/20 reducers. They are readily available

I have reducers but then the earthing ring doesn't fit

Get another adaptable box and put the gland in a 20 mm hole.

get a 25mm earthing ring then.

Why don't the banjo fit? You still stick it on the gland, not the reducer. Done it hundreds of times mate. Or have I missed something here.
