If you can change a 4-wire to a 3-wire 240V outlet circuit then what was the purpose of having a 4-wire box in place to begin with?

Answers ONLY for USA, Canada and countries using similar 60Hz mains supplies     You are not allowed to change a four-wire outlet to a three wire outlet. You can

Can a 10 amp circuit breaker be changed to a 15 amp without changing the wiring and what gauge wire is correct for 15 amps?

14 gauge wire is rated for 15 amps wich is the smallest size breaker that is used in the US. I never heard of or saw a 10 amp breaker and I am a licesened electrical contracto

Why is it not okay to use a fuse with a higher amperage rating in an electrical circuit?

The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed b

True or false if the voltage and resistance of a circuit stay constant the amperage can never change?

The equation for the three values in the question will give the definite answer.    Amperage (I) is equal to the voltage (E) divided by the resistance (R).    I=

How do you increase amperage without changing voltage or resistance?

You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changing

You changed 3 wire to a 4 wire on a dryer and keeps blowing circuit breaker?

Dryer plug three to four Open up the electrical access panel on the back of the dryer. You will see a terminal block with three wires going into it from the plug cord assembl

What is circuit amperage?

Generally speaking an appliance (eg tv) is supplied with power so when it is off it has voltage supplied. After yo turn it on it starts to draw power called amperage the volta

How do you change wire?

Spark Plug Wires? Remove them 1 at a time from the spark plug to the distributor or the ION pack, remove and replace the spark plug, add the new spark plug wire from the newly

Can you add another appliance to a circuit by simply changing breaker to a larger amperage?

The most sensible solution is to get a qualified electrician to check the wiring to see what the maximum load should be, and if necessary re-wire with higher capacity wire/con
