Control-panel termination planning
Electrical Ferrule Quantity Calculator
Calculate ferrules from conductor-end counts while keeping ferrule-per-end assumptions and procurement spares visible.
Ferrule schedule
Run separate calculations for different ferrule sizes or twin-ferrule requirements when the stock items are not interchangeable.
Enter conductor and termination counts.

Ferrule quantity method
Conductor ends = conductor count × ends per conductor
Base ferrules = conductor ends × ferrules per end
Planning ferrules = ceiling(base × (1 + spare ÷ 100))
Base ferrules = conductor ends × ferrules per end
Planning ferrules = ceiling(base × (1 + spare ÷ 100))
Example
120 conductors with two terminated ends produce 240 conductor ends. At one ferrule per end, the base quantity is 240. With 10% spare, 264 ferrules are planned.
Why conductor ends are the core quantity
Counting cables rather than actual conductor ends can produce serious under-ordering. A multicore cable schedule and a termination schedule are not always the same thing, so the endpoint relationship remains explicit here.
Frequently Asked Questions
Can ends per conductor be one?
Yes for one-ended termination schedules.
Can ferrules per end exceed one?
Yes when the approved assembly requires multiple ferrule components at a termination.
Does this specify crimping tooling?
No. It is a quantity calculator only.
