The size of the breaker is determined by the smallest conductor used in the system and by the type of load being serviced.

What is the engine 132kw AMP 980 volt speed 380 no-load operation when the engine was a no-load amps 58 amp motor power 132 kw Is correct

180 what?

Using AWG # 3/0 copper wire you will have a voltage drop of around 3.8% at 68 degrees Fahrenheit. This should be acceptable to your local inspector but you may want to call them and make sure.

That question can only be answered by someone who is familiar with local building codes. Contact a local electrical contractor for information regarding local building codes.

#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .

I would use AWG #4 for that run in alluminum. You will have a 3.8% voltage drop which is acceptible.

Yes, but they obviously cannot be simultaneously loaded their maximum loads because the 400-amp breaker will blow well before that.

Similarly, you can have multiple 100-amp panels fed from a 200-Amp main breaker, knowing that you will NEVER have 100 amps running in all panels at the same time.

AWG # 10

The clamp part is for measuring amps via induction. You set meter to amps and clamp around only a single wire. Device you are measuring must be operating. This means you couldn't clamp around a lamp cord to a table lamp since the current induced in each direction cancels out. You would have to separate the wires. An electrician would carry a short extension cord with the wires already separated. Most often a clamp meter is use to checks amps in a breaker panel on the black wire coming from the breaker.

I think you mean 2 HP pump. I am assuming a 220 To 240 volt supply and that should equate to about a 12 amp current. All my pumps use only a 30 amp breaker and 10 AWG wire.

Yes, different voltages can be placed in the same conduit, but there are specific guidelines that must be followed to ensure safety and compliance with electrical codes. Generally, conductors carrying different voltages should be separated by adequate insulation or barriers to prevent electrical interference and potential hazards. It's important to check local codes and regulations, as they may have specific requirements regarding conduit usage for different voltages. Always consult a qualified electrician or local authority for guidance.

NEC recommends maximum allowable voltage drops not to exceed 3% on a branch circuit. For feeder/ branch combos the NEC recommends that the voltage shall not drop by more than 5% to the furthest outlet.

The main consideration that is enforced is NEC 250-122. You must compensate your grounding conductor when you increase in conductor size to compensate for voltage drops.

Direct bury or conduit:

#4/0 copper provides for 2.95%

#2/0 copper provides for 4.35%

#1/0 copper provides for 5.19%

Interestingly enough, using a separate calculator 3/0 copper with 3% voltage drop can be 780.5 feet long.

600amps

The National Electrical Code (NEC) does not specify a strict limit on the number of duplex outlets allowed per 20-amp circuit, but it does recommend that you consider the load. Generally, it's common practice to allow up to 10 outlets per 20-amp circuit if standard usage is expected. However, if high-wattage devices will be used, it may be prudent to limit the number of outlets to avoid overloading the circuit. Always consult local codes and regulations for specific requirements.

12 AWG. You can run several hundred feet.

PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground

It depends on the use of the 10 outlets. 20 amp is the norm. If this is in a shop with heavy loads then you would have to break them up.

No, the electrical code requires that each be on it's own circuit.
