That would need a busbar, an aluminium one with a cross section of 1 cm by 9 cm (or larger).

A 600 MCM copper conductor with an insulation factor of 90 degrees C is rated at 475 amps.
A 300 MCM copper conductor with an insulation factor of 90 degrees C is rated at 320 amps.
A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.
These size wires can be installed in parallel 600 MCM, tripled for 300 MCM or grouped in four 3/0 wires groups to achieve the amperage required.
Special parallel, three barrel and four barrel lugs have to be used to make the connection to the required load.

For a 900 amp load, you would typically need very heavy-duty wire such as 600 MCM (thousand circular mils) or larger. The exact size will depend on the specific application, distance, and voltage drop considerations. It is recommended to consult with a professional electrician or engineer for a precise calculation.

What is the wire size for a 35 amp breaker to a ac unit?
You will need to use #8 wire.
What is the amp size of a 8 wire?
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
Can you hook a 15 amp and 20 amp breaker to a breaker box using 20 amp wire?
No, you should use wire that matches the lowest amp rating of the breakers connected to it. In this case, you should use 15 amp wire since one of the breakers is a 15 amp breaker. Matching the wire gauge to the lowest amp rating ensures the wire is protected from overheating in case of a short circuit.
What size ground wire is needed for 20 amp?
For a 20 amp circuit, a 12-gauge copper ground wire is typically recommended. This wire size can safely handle the current and provide proper grounding for the circuit.
What is the wire size for a 35 amp breaker to a ac unit?
You will need to use #8 wire.
What size wire do you need for a forty amp breaker?
8 AWG is typical.
What size wire do you need for 100 amp service if you use alunimum?
2AWG.
What size wire do you need for 42 amp circuit?
For a 42 amp circuit, you should use at least a 8-gauge wire to ensure it can handle the current safely and prevent overheating. It's always best to consult the National Electrical Code (NEC) or a licensed electrician for specific wiring requirements to ensure compliance with local regulations.
What size gauge power wire do you need for a 4000 watt amp?
2 or 4
What size wire for 72 amp motor?
You will need AWG #3 if it is a short run.
What size wire and breaker do you need for a 200 amp continuous duty circuit?
AWG 2/0 copper wire.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What is the amp size of a 8 wire?
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
What size wire do you need to run 100 ft 75 amp 230 volt?
Depends on the size of the circuit which you did not list.
What size hot wire do you need for a 1900 watt amp?
A 12 gauge wire can support a load of approximately 2200 watts.
What size gauge power wire do you need for a 1200 watt amp?
You should use a 4 guage wire. There is a handy chart located at http://www.the12volt.com/info/recwirsz.asp which lists the proper wire size for differing wattages.
