Hi all,
What are my chances of getting two 4mm^2 cores into a single MK 20A grid-switch terminal?
Cheers,
Colin.
Quick electrical question.

Slim, I think. The switches are all made to comply with BS EN 60669-1, which only requires 6 mm^2 terminal capacity for current ratings of 16 to 25 A.
A call to MK tech support would give you a definitive answer though.
google mk gridswitch terminal capacity and it comes up in the technical data sheet
1 x 6 mm2 2 x 4 mm2 3 x 2.5 mm2 4 x 1.5 mm2 4 x 1 mm2So, every chance.
You mean too fat!
You really need some intermediate connection outside of the area with constraints of size I think. Brian
Thanks for that. Your Googling is definitely better than mine. I can confirm that they do fit (just) since I got a switch today.
I suppose that means I can't get out of starting the job any longer...
Cheers,
Colin.
