HI All
I'm thinking of replacing the main relays in my 7.5kw glass-fusing kiln
with these relays
https://ie.farnell.com/potter-brumfi...rTechnicalDOCS

- which are Potter&Brumfield DPDT 40A relays.

Currently I'm using domestic contactors, which last a few years (not
through being overloaded, simply through the number of on/off cycles
they go through during each firing schedule).
The contactors have screw-down clamps for the connections.

The Potter&Brumfield relay uses 1/4" 'Faston / Lucar' connectors.
Out of curiosity, I looked on the web for the current rating of these
connectors - Wiki claims "24A (continuous)" with 10AWG wire (about
5.2mm-squared).

Any thoughts on this - or how a relay rated at 40A has connectors rated
at 24A?

My plan was to find the sturdiest Lucars I can locate, crimp them onto
the mains feeds and (?perhaps?) run some solder into the crimp - just to
be sure.

What does the team think?
Thanks
