Introduction: I'm in the alarm industrie and there is something we all do but I never questioned my self if it is good or not. Recently, some guy from the technical support department of honeywell told me that is not good.
- We use most of the time a wire 4/22 to do our work.
- When we have to "power" our equipment we normally "double" the wire like : "red-yellow" / "Black-green" to drop the resistance.
I know that do not make a bigger wire but it should help.
Situation: - The power supply is 9vDC - The manufacturer said : No more than 11' and double wire do not change anything.
The Question: What are all the real impact of doubling wires in any situation ? (AC and DC, power, communication, etc)

The guy from the manufacturer told me that the method of using 3 wire to match the AWG do not apply because it is in DC ...
It is true that it will not react the same AC / DC ? I know that DC drop faster than AC but how it is accurate in this situation ?
