Never seen these before....

Doing an EICR and came across this Square D board. Must be one of the earliest RCBOs, unless you know different????

Seen plenty of those before. What were the trip times like out of interest ?

I've got about 50 of the mcb's in a box, I always save the old stuff when upgrading in the factories.

I must lead a sheltered life! The trip times on two were really good on both 1 & 5. The third was 120ms on x1 but something around 17ms on x5.

Ah, I might be looking for two 16 A, if I can't find the break in one of the RFCs!

Although I have seen plenty they are not all that common. The Square D domestic boards often seem to have come with a ELCB main device instead.

got a farm with them. built in the 70's. to reset, you need to flip them fully down, then up.

I bought one of these boards to practice my CU wiring - was considering gradually populating with the RCBOs and using it in my house but I may as well buy new - after all it was second hand for a reason. Solid CU though and non combustible!
