Want this question answered?
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
This is a voltage drop question. A voltage must be stated to answer this question.
How to calculate a cable size of 3kw motor
what size sprockets are neede for a gsxr 600 k7
15 millimeter
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
Cannot answer this question. Will need to know the voltage and amperage of the circuit. Also need to know the application i.e. is it a lighting circuit or a motor circuit?
7 mm. You can buy this.
If this question is asking about voltage drop, to size a wire, a voltage is needed.
AWG 10 guage.
4sqmm
Connect the circuit to the appropriate size circuit breaker to meet the required amperage of the circuit. Turn the breaker on and use the circuit. Unless the circuit is of a very high ampacity, plus 200 amps, don't worry about voltage drop over 50 feet.
