A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 800 feet on a 120 volt system. 500 MCM wire diameter is 1/2 inch. As you can see there will be trouble getting that size wire into a 50 amp breakers lug. On installations like this to offset the voltage drop at such a low voltage, a transformer should be used at both ends. The first transformer to raise the voltage and the second transformer to lower it at the 800 foot end. If you use two 480 volt Transformers a #1 wire can be used between them.
A #1 copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 800 feet on a 480 volt system. By increasing the voltage you can see that a smaller wire size can be used.
On an installation of this nature, a primary line should be brought to the RV site and a service distribution panel established at that point and any RV vehicles can then be fed from that service.

What is a non auto circuit breaker?
A non-auto circuit breaker is a circuit breaker with the trip element removed. Basically, it is a modified circuit breaker that is now a disconnect switch (glorified disconnect switch).
Is it ok to change a breaker box in a house from 2 fuses at 50amps to one at 50 and one at 35 amps?
Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
Can you use a circuit breaker as a mean of disconnect?
Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
Can a 220 Volt well motor be added to a 200 amp box or does it need its own box?
The well pump breaker is installed in two slots in your breaker box. You then run the correct size cable for the amperage of the pump to the area where the pressure tank is located. install a breaker or disconnect on the wall near the pressure tank and then connect the low pressure switch to the disconnect. Connect the pump to the low pressure switch.
Will a circuit breaker function the same if supply and loads are reversed?
Yes, a circuit breaker will function the same if supply and loads are reversed. This is the way that some sub panels are fed instead of a main disconnect at the top of the distribution panel.

How do I know if I have a 30 amp breaker at my house to plug a trailer into?
If it is a 30 amp breaker then it is a 240 volt outlet.

When replacing a dishwasher what do you disconnect first?
The electricity. -Turn the breaker OFF first.

How do you replace a 15 amp breaker in the circuit box?
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
How do you disconnect power?
By unplugging the device in question or turning off the breaker for the fixture in question.
No, This has nothing to do with your breaker box. It plugs in and distributes low voltage power to security cameras.?
No, This has nothing to do with your breaker box. It plugs in and distributes low voltage power to security cameras.
What is the definition of a load center in the 2008 NEC code book?
In the CEC there is no definition for a load center. In layman terms a load center is; A distribution panel that does not have a disconnect breaker in the same enclosure. A distribution panel that does have a disconnect breaker within the enclosure is called a combination panel.
What should you do if the breaker in a trailer keeps tripping after five minutes?
You should first check to see if you are not overloading the outlets. If you are, just unplug something and reset the breaker. However, this is also a symptom of circuit breaker failure. In that case, replace it with the same amperage breaker of the same or compatible brand.
What is tripping relay?
You need to remove everything connected to the breaker and see if it still trips. If it does it is in the wiring or possibly a bad breaker. Disconnect load from breaker and see if it still trips. If so replace the breaker. If it still trips and is not the breaker then you will have to start pulling each outlet from wall and checking after disconnecting each outlet.
What does the trip free characteristic of a circuit breaker mean?
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
