It's possible. It's not right though. Run a separate wire for your 110v circuit. <><><> To follow NEC (National Electrical Code) guidelines you need two separate branch circuits: 240V and 120V.

Each circuit should have its own breakers of the correct size. Wire sizes will depend on the length and ampacity of each cable.

The outlet types required for each circuit will depend on the appliances to be served and, according to their locations, GFCIs may be necessary too. <><><>

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.

What gauge romex for outlets?

Romex is a manufacturer's wire cable trade name, the 10 refers to the size of the wire inside the cable set. A #10 AWG copper conductor with an insulation factor of 90 degrees C is rated for 30 amps.


What wire is commonly used in house wiring?

Romex, All you have to do is go to a hardware store and tell them you need house wire. It comes in a box. I am not sure how many feet. If you are just looking for the gauge, they will know that too.


Is that possible to run romex wire to the under ground basement?

If the wire is to be buried you'll need to use "direct burial" wire; if you're staying inside the house, just under the floor and above the concrete or dirt, standard romex should be fine.


WDR type outlet?

A fire trap outlet used in motor homes. The wire self pierce romex conductors with a small contact friction contact. These should be replaced with quality screw terminal outlets in outlet boxes.


Can you add 14-2 romex wire to old house wiring?

Yes, if the existing wiring you are adding to is 14 gauge. If it is 12 guage then you must use 12 gauge. If you are running wire from the service panel it is fine as long as you install a 15 amp breaker.


How many watts and romex gauge is safe for a 15amp breaker?

Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80&amp; of maximum. You need 14 AWG gauge wire.


What sorts of questions are on the Journeyman Electrician License Exam?

What gauge of wire is required to carry a certain amperage X number of feet? How do you break out a 120 volt circut from a 3 phase line? When installing a load center, how should the ground be installed? What locations require Ground Fault Interrupters to be installed? How should a 240 volt dryer plug be wired? What is the minimum size conduit that 3 0 gauge wires can be pulled in? Can 12 guage Romex be used to wire a water heater?


Is romex pure copper?

Copper or aluminium.


What size romex for 5000 watt dryer?

Assuming 220 volts service 5000/220 = 22.72 Amps. That equates to 10 AWG Romex.


What is the difference between 15 amp and 20 amp service?

It is the rating of how much current you can deliver to loads on a circuit. For example, if you had 10 outlets on 20 A service that is what you could run from the outlets on a circuit. This is a total capacity and not the capacity of each outlet on the circuit. If you plugged something into an outlet that drew 20 A you wouldn't be able to run anything on other outlets. In a lighting circuit two 60 W incandescent bulbs draw one amp. Therefore, on a 15 A lighting circuit you could have a maximum of thirty 60 Watt bulbs. Usually you try and stay at about 80% of rating so practically you could have 24 bulbs. ponypomp; 5 amps. A 15amp breaker is used with 14ga romex wire, designated in homes for lighting. Common practice. A 20amp breaker is used with 12ga romex wire ,designed for the outlets in a home. Common practice. Just wanted to add this to the great post above.


What is the difference between thhn and romex?

THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
