The minimum allowed conductor for 120 volts, 15 amps at 325 feet would be 6 AWG, giving you a 4.8 percent voltage drop (at 18.75 amps, which is the derating for 15 amps being 80 percent of the design load). Five percent is the max allowed in US and Canadian electrical codes (US measured at outlet, Canadian measured at point of use). If you're using 240 volts, the min AWG would be 8 AWG for 3.8 percent drop.
A 350 MCM copper conductor with an insulation rating of 90 degree C is rated at 350 amps.
For a 300 amp three phase circuit breaker, you should use wire that is rated for at least 300 amps. The wire gauge needed will depend on the material (copper or aluminum) and the installation method (conduit or cable), so it's recommended to consult with the National Electrical Code (NEC) or a qualified electrician for the specific wire size required. Using the correct wire size is crucial to ensure safety and prevent overheating.
Electrical breakers are sized by the conductor that is connected to it. The conductor is sized by the current that is drawn by the circuit. The formula for amperage is I = W/E. Amps + Watts/Volts. 325/120 = 2.7 amps. A #14 copper conductor is rated at 15 amps. This is the minimum size wiring that is used for house circuits loads. The breaker for this size wiring will be a 15 amp breaker.
325
A 350 MCM copper wire with an insulation factor of 90 degrees C is rated at 325 amps. If the question is referring to maintaining a load of 300 amps then you have to up size the wire size because the conductor is only allowed to be loaded to 80%. A 500MCM copper wire with an insulation factor of 90 degrees C is rated at 395 amps x 80% = 316 amps.
A motor that is rated at 250 full load amps will need 400 amp time delay fuses or a 500 amp frame breaker with adjustable amperage trips. The wire size for this motor has to be 125% of the motors FLA. 250 x 125% = 312 amps. A 350 MCM copper conductor with an insulation factor of 90 degrees C is rated at 325 amps.
The 1993 BMW 325 radio wiring colors are red, brown, green, yellow, and white. The red wire is the positive wire. The brown wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.
.044mm
A 250 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated at 255 and 265 amps respectively. This conductor can only be load to 80% capacity which allows a working current of 204 and 212 amps respectively. To obtain the full capacity of 250 amps a 350 MCM conductor will be needed. The amp rating for a 350 MCM conductor with an insulation factor of 90 degrees C is 325 amps. 325 x .8 = 260 amps.
325 amps but i go with 700 if cold and u have air, power windows
well, if 33'' is 305, then 325 must be 35''
