Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
Can you use 14-3 wire on a 20amp breaker?
No. A 20 amp breaker needs 12 gauge wire.
Can you use a 15amp outlet on a 20amp circuit?
No. You aren't allowed to install a device rated greater than the circuit is rated.The 20 amp receptacle would allow you to plug in 20 amp loads (which is why it is different than a 15 amp receptacle), and plugging a 20 amp load into a 15 amp circuit would cause an overload and the 15 amp circuit breaker would trip.ADDITIONThis may still be open for discussion. According an electrician from RKO Electric, you can in fact install a 20 Amp GFCI receptacle on a 15 Amp breaker. Apparently, the breaker will trip well before the receptacle is able to pull 20 Amps of current into the line. Please see the following link from another website: http://en.allexperts.com/q/Electrical-Wiring-Home-1734/20-amp-GFCI-outlets.htm2003 NEC Code Book says:210-21(b)(1), p.70-42: A single receptacle on an individual branch circuit shall have an ampere rating of not less than that of the branch circuit. To me this indicates that if there's only one receptacle on the circuit, you can't have an outlet rated for less than the circuit, but it neither mentions nor prohibits oversizing the receptacle.210-21(3), p.70-42: Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in table 210-21(b)(3)... which says: 15amp circuit, not over15amp receptacle (
Can 3.55 watt oven run on 20amp hard wire?
To answer this question the voltage of the oven must be stated. Also double check on the wattage of the oven 3.55 watts seems low. Maybe it should be 3.55 kWs. Amps = Watts/Volts.
What size wire to use for a 800 ft run on 20amp circuit?
To answer this question you have to know the voltage and load type. If this was a 110 Volt lighting application 12-2 should work. If this was a 220 Volt motor load 10-2 might be a better choice. Copper wire 120 volts #6, at 240 volts #8. Aluminium wire 120 volts #4, at 240 volts #6. 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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
