Once the fireworks are sorted, loaded, and numbered with tin foil, Fuse Boxes are then installed onto the sides of the racks and left unplugged. Fuse boxes are numbered, and will be connected to the corresponding firework number using a Squib.
A squib, is an electronic wire with 2 exposed wires on one end and a prosperous tip on the other. The 2 exposed wires connect to our fuse box using speaker spring clamps, while the prosperous tip is embedded into the tail end of the firework’s fuse. When an electronic signal is sent from the fuse box, current travels through the wire and ignites the prosperous tip in turn igniting our firework’s quick fuse remotely. Wiring these squibs requires the majority of the day.
Finally, once the fireworks are connected to the fuse box via a squib, the fuse boxes are then connected to our Control Panel and the team tests for continuity. Once the connections are verified and all shots are accounted for, it’s time to take a break and wait for show time.
On July 5th, our crew gets breakfast at Betty’s Place (as per tradition) then finishes cleaning up!
TLDR:
Fireworks are placed in a tube, which are mounted on a rack. A wire from our control board extends to a fuse box where a squib bridges the connection from the fuse box to the firework’s fuse. When an electronic signal is sent from the control board it is sent to the corresponding fuse for the corresponding firework number. Then boom! America.
