I have an issue where I need to downgrade Class 1 control wire to Class 2 or 3 before a distribution block.
The transformer panel has a 350VA transformer 120:24VAC. The hot leg goes to a 6A fuse then both legs go to a controller panel. In this panel, the hot leg goes to a fused terminal block of varying fuse sizes (0.5-2A). From the 2A fuse the 24VAC then goes out to multiple command discreet outputs.
As I read the NEC, I believe the wire is still rated as Class 1 out to the commanded devices. This really limits my conduit choices. What component can I add to the circuit in the transformer panel to downgrade it to a Class 2 wire?
Thanks for your help!
