Hi everyone! I'm new to the fireworks industry (by new, I mean I've assisted with one cat 4 display). I am starting from the very bottom, but I already have an idea of the different types of fireworks. What I want to explore is the difference in wiring fireworks with e-matches, when electronically firing. As far as I am aware, there is series and parallel. Can anyone tell me the main difference and a rough idea of how the wiring goes (and which one is most common)? I've done this once before, but that was about 5 months ago and I've since forgotten. Thank you.
