In order to calculate the voltage drop, we would need to know the exact conductor size of the wiring. Of course the circuit is actually going to be 22m in length. You can (fairly) easily measure the voltage drop with a voltmeter, to measure the voltage at both locations while the load is applied. Normally one would not expect a significant drop at 0.9 A over 11m of a wire chosen carefully for the job.
However, all joints in the wiring, including switches and breakers need to be considered, before blaming the wiring. Bob Dircks On Sun, Mar 5, 2017 at 11:32 AM, Future Aviation Pty.
