A 12 gauge wire can support a load of approximately 2200 watts.
#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 .
Service entrance wire should be AWG #3 copper.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
6 AWG.
AWG 10.
Need to know the voltage of the mixer.
2 or 4
In a floor lamp or table lamp a #16 wire is what you need.
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.
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
10 gauge will suffice.
Yes, if the elements are operating simultaneously, you would need to have sufficient ampacity (wire size) to supply both. If they only alternate, one at a time, you could use a smaller wire.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
4 gauge
Information is incomplete. You need to know the load in Watt or Kilowatt and the voltage on the secondary side to determine the load current, on which the size of the wire is designed.
AWG # 10 wire on 30 amp circuit.
on a 4000 watt amp the best gauge wire woul be between 2 and 0
