Just so I can understand, can you briefly tell me why.
Ok. No problem.
Looking at the diagram please note that the Neutral is connected to the contactor coils that draw less than one Amp total. Then it connects to power input for the JSL-71 timer > less than 1 amp. Then it provides power to the 2 pump outlets for a total draw of less than 4 amps. From there it goes on to the SYL-2352 PID input power and switch indicator lights. The total draw on the Neutral circuit will be less than 6 Amps.
Also please note that every device that uses the Neutral line has its 120V hot fused seperately. With this setup much smaller wire can be used for every device except the 240V circuits powering the elements.
That's it for the Neutral.
The 240V 10 awg circuits are the blue
lines going to the contactor points and then to the elements and the red
lines going to the SSR and then to the contactor points and then the elements. The only 240V powered devices are the 2 heating elements and the element indicator lights.
Hope this helps and makes sense.
