Please see attached schematic for reference:
Question: A company designed a unit that's powered by two transformers (380VAC to 24VAC and the other 380VAC to 120VAC). There are three circuit breakers (CB1 60A, CB7 4A, and CB8 8A) which are positioned before the transformers.
The problem is CB7...
For a miniature model set, I'm trying to make a 3-way (red, green, and yellow) traffic light blink on and off using a basic circuit design.
Green light: Turn on for 5 sec then turn off for 3 sec
Yellow light: Turn on for 5 sec then turn off for 3 sec
Red light: Turn on for 5 sec then turn off...
