The E-Stop is fused with a 1A fuse.

You mention 50A service "coming in". The particular diagram in this thread is drawn for a 30A 240V service feed. If your intent is to power it with a 50A service feed, you MUST provide circuit breaker protection within your power panel.

I understand that. I had seen another one of your diagrams that had the same setup(for the emergency stop) for 50 amps. It went from the line2 distribution block to the 1a fuse to the resistors to the switch to the ground. I just assumed that the emergency stop setup would be the same. I guess I should have started my own thread.

Question for the questioners: Doesn't anyone read the Legend: at the bottom of the diagram?

Switch #1 is clearly referenced as a DPDT Center Off 25A unit. I even reference the source.

i looked at that legend no less than 100 times,lol i even printed it out. im not good at understanding schematics and such yet. but i'm learning.. i apologize in advance for all of the other stupid questions I will ask in the future.
