Banjo

[Batch]

How come MICC glands don't with a banjo where as SWA does, yet both are required to the connected to earth or are used as a CPC?

Because you use the pot to earth the MIMS, which has a earth connection attached to it.

Sorry are you talking about the pots with the soldered earth connection inside?

On the termination iv done, its only been 2 core into a metal back box.

 

[Plonker 3]

Yes that's the one, you buy them with it per soldered.

If your pot is missing the earth tail then a banjo can be fitted to meet requirements....

If the pyro gland back nut isn't tightened up onto the olive then a banjo/frying pan isn't going to do much. Earth tail pots aren't really needed unless glanding into plastic, geez bare pyro now that takes me back.

did a load of bare copper pyro on a furnace back in the 60s single cores and multi cores,we had to paint the galv tray with red oxide before cabling

....But did you fit any benjis, sorry I mean banjos?

Pot earth tails weren't around, and banjo's weren't really required when i first came into the industry, ....but i can't think of a single instance where we didn't achieve dam good earth connections. If your that bothered about a MICC not giving you a good earth connection, use Piranha nuts, far better than a banjo...

Still come across loads of 70's/80's installed pyro's in schools without earth tails and never ever see poor continuity.....was done proper like in them days:hurray:

Installed loads of pyros prior to earth pot tails arriving on the scene, never any problems. Only time ever fitted banjo's.....with swa.

It all comes down to the item/equipment you are terminating into. If its a besa/metal conduit box and you are using the threaded spout then no banjo is required for either micc or swa cable.

Our fire alarm installation over the whole project is wired in MICC, i'm pretty sure that we are not using pots with incorporated earth tails on our installation. I know we didn't on the last project. And i won't be giving it a second thought either!! lol!!
