The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html
Hope that helps.

How do you get -48v DC?
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
What is the Formula to know about of dc cable size in mm?
how to know dc cable sizes
How do you wire -48v dc power and ground to earth?
always think of any supply system so : RED = MOST POSITIVE BLACK = MOST NEGATIVE in a telecom system the -48V supply is refferenced to ground and earth, so the supply wire is NEGATIVE, this means a DC supply most positive signal the RED wire, go to EARTH = ZERO, the BLACK wire is the MOST negative, so in this case it is -48V
Why is a rectifier needed for a GSM BTS?
This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation So the main function of this is 1) To convert AC to DC 2) To control overloading
What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.

Why telecom power supply has 48V dc power supply?
because the termination and relays in side the telecoms penal needs for DC supply to continues the protection equipment and relay and purpose of telecoms
Minimum cable size for 12v dc?
It depends on the current requirement. Specify an application or describe what is being powered by the 12 V to get an answer.
Can you convert ATX power supply to run off DC input 24v 48v or 120v?
Like to run on a DC powered machine? Probably the easiest and safest way would be to buy a standard power inverter.
How many volts does a bts uses?
By BTS, do you mean Base Transceiver Station? Such equipment can be found in cell phone towers. Usually a BTS runs on 48V DC.
What will be the voltage drop across two core cable whose length is 1500m and voltage is 24v dc and load is 2watt?
There is insufficient information in the question to answer it. You did not provide the size (gauge) of the cable. Please restate the question.
What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.
Can AC cable use for DC motor?
Yes, what matters is that the cable can take the correct voltage, and is thick enough to carry the required current, but ac or dc makes no difference.
Can you plug a dc appliance into a wall outlet?
With the proper cap configuration on the DC cable, yes it physically can be done. If there is a DC load connected to the end of the DC cable, the load would be destroyed by the application of AC voltage being applied to it. Why anyone would consider doing this type of procedure is anyone's guess.
