Yes, finger-tight torque. Thatís especially common on the thermocouple oval connection block. Most replacement thermocouples have loose screws.
Iíve been delivering new 12-sided kilns to schools, which entails taking the kiln sections apart to move them through 36Ē doorways. While Iím at it, I check the connections to make sure theyíre tight, and I rearrange the thermocouple wires if theyíre too close
to relay wires in the switch boxes.
Iíve noticed lately that the push-on terminals on new kilns arenít as tight as the older push-on terminals. (I have to remove wires to separate the kiln sections. Thatís why I know how tight the terminals are.)
The push-on terminals should be so tight that theyíre difficult to remove.
One thing electricians have in common: their connections are very tight.
