Be careful. This question can have more than one valid answer. For instance, table 310.16 may apply in some circumstances, but if the 200A service in the question happens to be a single-phase service in a dwelling, there is a different table (310.15(B)(6) just for the purpose of sizing service conductors in that case. It indicates that 2/0 copper OR 4/0 aluminum would be the correct choice.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 9y agoThe wire size is based on the connected load or the size of the sub panel main bus bars. Once this determined then the proper over current protection has to be installed.
It is a complicated job in as much as you have to know wire sizes, ampacity of wires and proper electrical workmanship. My suggestion is, for such a project it should be left to a licensed electrical contractor to take out the proper permits and call for proper inspections. By taking this route it will leave you confident that if any mishaps happen to the installation down the road your insurance company will be behind you 100%.

What gage wire is used for a marina shore power 100 amp circuit breaker?
0 or if it a main breaker in a service entrance you can go down to #2 <<>> A #3 copper wire with an insulation factor of 75 or 90 degrees C is rated at 100 and 105 amps respectively.
How thick is 26 gauge steel in mm?
For a wire classified under American Wire Gauge standards, 26 gauge wire is 0.0159" (0.40386 mm) in dameter. For a wire classified undere metric wire gauge standards, a 26 gauge wire is 2.6mm in diameter. Metric gauges are calculated simply by multiplying the diameter, in mm, by 10 and therefore increase as the diameter increases, unlike the AWG standard.
Short distance transmission of power is done at higher voltage or higher current?
High voltage is used to transfer power over long distances ONLY because the gauge of the wire can be smaller. Power transfer is always most efficient at the operating voltage if the size of wire is not an issue.
What is AWG in cable?
American Wire Gauge. Measure the thickness of the cable.
What is thicker 12 gauge or 18 gauge steel?

Is an audio signal affected by wire gauge?
Absolutely for maximum power transfer impedance's are to be matched a low wire gauge will insure that the power is not dissipated on the wire as appose in the speakers.
What is a good wire gauge for a car radio?
A good wire gauge for car radios is 18 gauge. This wire runs between the radio and its power supply from the vehicle.
What is the orange wire on your fuel pump harness for a 1990 ford f150 used for Is it a power wire?
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.

What does GA for tubing stand for?
the answer is gauge its a measurement of thickness in wire the 4 gauge (ga) wire ran from my car battery to power my audio amp. the smaller the number the bigger the wire usually from 24 gauge to 1/0 gauge which is about a inch thick
What gauge is use on low votage?
The lower the voltage the larger gauge wire you will need to get the same power.
How much does a power cord cost?
Length and wire gauge will determine this for you...
The temperature gauge stopped working on your 95 grand am what could it be?
check the power to gauge and the temperature sensor (tps). if no power broken wire or short to ground. if power to both areas bad gauge.
What is gauge 8 means in copper electrical wire?
In cooper electrical wire, gauge 8 means the wire size assigned by the American Wire Gauge (AWG) system. That is why you always will hear about AWG WIRE, it's not the type of wire is the gauge that we are talking about. A gauge 8 wire will be used for connections requiring from 40-45 amps to a maximum of 73 amps. (24 for power transmission). Diameter of an 8 AWG wire is 0.12849 inches. 8 AWG is solid, not stranded.
What are the wiring color codes for car stereo in a 1989 caprice classic?
