Original answer: Yes! I did this in my Kitchen USSEG: It really comes down to how much amp each of the appliances is going to use at peak. You need to look at the emperage …draw of each appliance then make your decision. If you are sure you are not going to use both at the same time (ever) then it is fine. A disposal requires at least a 15 amp and a dishwasher usually needs at least a 15 amp. If breakers start tripping you will need to separate them. If this is for new contrstruction, there is no reason not to run a separate line for each.
Wire sizing charts are available on the web. For your situation, use at least 12 gague wire.. See also, this helpful chart: http://www.worldchat.com/~sva-sales/html/wire_sizi…ng_chart.html
14 wire is rated for 15 amps. If the load is going to be continuous the wire can only be loaded to 80% so you would have to use a # 12 rated at 20 amps. 20 x 80% = 16 amps.
Yes a remote wire is necessary. You must wire the remote wire from the amp to and ignition source of power (a component which turns on when the ignition in the car is engaged.…) i.e. the radio. The remote wire signals for the amp to power on.
Answer for USA, Canada and countries running a 60 Hertz supply service. A dedicated circuit of #14 copper wire fed from a 15 amp single pole breaker is all that is needed for …a dishwasher. 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 IF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
12 gauge or bigger.
4 sq.mm cable
A #14 wire will do fine for grounding a 20 amp device. That is the size of the ground wire in a 2 conductor # 12 wire building cable.
A #12 copper conductor with an insulation factor of 60, 75 and 90 degrees C is rated at 20 amps.
A contactor is nothing more than a switch but it is electrically operated instead of mechanically operated as you would find with snap switches in your home. As with any swi…tch, you need to make sure it is rated for the voltage and amps you intend to feed through it. You will have a pair if terminals for each hot wire. In addition you have terminals for the coil that operates the contactor. Very often this is a smaller voltage but not always. These control wires may be connected to any piece of control equipment, which may be a snap switch, but may also be a thermostat, light or motion sensor, or various types of hydraulic sensors such as pressure, flow, or float. In today's technology the coil may be activated by computer signal which may be reading many different conditions.
12 AWG. You can run several hundred feet.
12 AWG in most circumstances.
I would use 4 AWG copper to be safe.
It's going to take a whopper of a wire to run a 20 amps 650 feet.I'd feel more comfortable if a journeyman electrician would come byto access my answer. But, my calculations s…how it would take 4 AWGwire to do it. If you want you could run two 7 AWG wires inparallel.
