How many igniters can I fire?
The table below will show you the number of e-match firework igniters you can fire on a length of our firework firing wire.
We assume ...
- e-match needs 0.8 Amps of current to fire.
- e-match has a resistance of 1.5 Ohms.
- Firing Wire is 2-core so the distance is the distance between the firing system and the igniters.
This covers the vast majority of e-match igniters with a good safety margin.
Parallel connected e-match igniters
12 Volt Output Firing System
We assume our 26 AWG Fireworks Firing Wire is used.
| Wire Length (M) | Wire Resistance (Ohms) | Max current available (Amps) | Max e-match in Parallel |
|---|---|---|---|
| 10 | 2.7 | 4.5 | 6 |
| 20 | 5.4 | 2.2 | 3 |
| 30 | 8.0 | 1.5 | 2 |
| 40 | 10.7 | 1.1 | 1 |
| 50 | 13.4 | 0.9 | 1 |
| 60 | 16.1 | 0.7 | 0 |
