Just purchased a wiska combi box 308/5. The SWA gland screws in but the earth tag has to be fitted on the outside (no room inside) so how do I get the earth through to the terminal box inside? - solder wire to tag pass through box to the terminal block! (ip67) Mmmm

Mike, assuming you got what Malcolm suggested, it should all go together like this...

Edit: above's sounding a bit patronising (not meant!) or...

screw the gland tight on to the box with the banjo (earth tag) flush on the outside.
Drill through the banjo hole then use brass nut, bolt (head external) & washers to secure the earth on the inside, ring crimp best.

I'd agree with Archy's first method of using the wiska earthing plate.
The second option is fine for a metal box, but on plastic the bolted connection can become loose as the plastic "flows" over time.
 
Thanks, I agree the earthing plate is best, but where can I purchase this item? Most electrical suppliers have the wiska box but not the earthing plate!! strange-why (cost).

PS. located a supplier TLC. Cannot gain entry through the rear of this box (mounting clip) so will have to go through the side using a 2.5 TE gland.

Question - Wiska 20mm ports do you have to remove the seal membrane before fitting the SWA gland?

Hi Mike,

Not sure which box you got, I think this the best one... 30 Amp Wiska Junction Box 85 x 85 x 51mm - Grey IP66
Ask your suppliers about Pirahna nuts, the canines danglies. Piranha 20mm Earth Locking Nut

As for the rear entry, drill a 20mm through the back and solvent weld PVC pipe into it. Totally waterproof!
 
Mike, will you let us know if this ever gets finished.

I’m sorry but so far it’s taken up more computing power than NASA had available to launch a Saturn 5.
 
Tony, Sure, will send pics (if I am allowed to) just to prove it is a genuine project. Sorry, I had not realised the forum was so limited in computing power!!

Regards.
 
..... but so far it’s taken up more computing power than NASA had available to launch a Saturn 5.

That is very probably actually true.
When PCs first appeared in the early 80s they had more computing power than they had on the Moon missions. It's quite amazing they actually did it, numerous times.

I’ve still got the invoice for my first PC. I got 2p change out of £1200 for a 80286 with 1Mb memory and a 40Mb drive!
 
Sorted the wiska/gland problem and plan to do the job over the weekend - will send pics although Tony might blow his rom with a few jpeg's added to the post!!


Mike.
