What size aluminum wire to feed 125 Amps 220 volt a distance of 175' and what size ground?

A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.


What is the cable size for motor 15kw 440 volts connection?

The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.


Is it common for electric bathroom vent motors to trip an GFCI receptacle?

Unfortunately GFIs don't like motor loads. The start up current required to start the motor is often 125-150% of the running load current draw. This initial spike in current draw when the motor is energized is sometimes "misread" by the GFI as current going to ground or an imbalance between the hot and neutral current. If your GFI has tripped numerous times, it is likely getting "weak". Try replacing it first. If it still continues to trip, replace your vent fan motor.


How do you calculate size of electrical panel?

The sizing of an electrical panel is based on the total connected load. Most new homes today will use a minimum of 200 amp panel. This size distribution panel will give ample room for expansion in the future. As more and more appliances and larger connected loads appear on the market, distribution panels have gone from 30 to 60 to 100 to 125 and now the standard is 200 amps.


What is the capacity of a 35mm2 cable?

Current carrying capacity is different for aluminum from that of copper cable. Under different conditions like, type of insulation, number of conductors, in conduit, underground, in air, single or multilayer, system voltage, the current carrying capacity varies a bit. Hence You must refer a standard chart from a reputed cable company.
