as soon as I plug-in a typical heating pad or a hair dryer into any kind of bedroom duplex, the lamp dim; and/or trips the circuit breaker. The house is of new construction-- placed in service 31 Dec 2013. My concern is: can I safely change the currently 15 AMP Breaker through that the a 20 AMP? . . . The business cable is of 14 Gauge Copper Conductor.

No!

The only safe way to increase the circuit"s capacity is by replacing the wire with among adequate gauge. Because that 20 amps, 12 AWG copper is sufficient for up to about 100 feet.

You are watching: Can i replace a 15 amp breaker with a 20 amp

If you just replace the breaker, the wire deserve to overheat and ignite the building from inside the walls.

To resolve the dimming issue, examine that the outlet is in good condition and that the wires room securely fastened and also not showing any kind of signs that overheating: blackening or lose of the copper shininess. Also, examine the finish of the wire inside the organization panel, both neutral and also "hot" (black) wire. If those room okay, collection the appliances come a lower wattage setup or change them with lower wattage models.

Absolutely NOT.

National Fire Protection agency (NFPA) standard Number 70, National electrical Code (NEC), adopted by many states (exceptions room Missouri, Mississippi and also Arizona), calls for the branch circuit Over current Protection machine (OCPD --typically a circuit breaker (CB) nowadays, rather than a fuse native days that yore) to protect the cable/wiring buried in your walls from overheating by de-energizing (shut off/open circuit) every outlets (lighting & receptacles) for the circuit by tripping/blowing.

Lights dimming and also CBs popping is a sure authorize your residence was not constructed to handle heating blankets and hair dryers in the bedroom. Swapping the end a 20 amp breaker because that the 15 amp breaker will violate NEC 210.19(A)(1) and provide cause for your insurance company not to reimburse her losses indigenous fire & exhilaration damage and also the water damages from the fire department flooding your house.

Wire is made smaller sized when produced by drawing/stretching it. The much more times its extended the smaller it gets. This is why American wire Gauge (AWG) seems backwards, i.e. 14AWG has actually a smaller sized diameter 보다 10AWG since it was extended more.

15 amp rated circuit breakers use 14 AWG present carrying conductors (black warm & white neutral) + a eco-friendly ground wire which generally carries no existing in market standard external white non-metallic sheathed cable called NM-B 90 degree Centigrade rated "Romex".

20 amp rated circuit breakers use the exact same configuration but 12 AWG, i m sorry is a bigger diameter wire than 14 AWG, and therefor has less resistance because that the exact same distance/footage indigenous the pack center/panelboard circuit breakers. 12 AWG NM-B sheathing is fancy yellow.

10 AWG v orange sheathing would certainly be even much better electrically, but an ext expensive and not compelled by "code", the NEC.

Blame every this mumbo jumbo top top Physics and also a German called Georg Simon Ohm who produced a regulation that also Donald J. Trump card can"t repeal. Voltage ns (V) = current (i amps) times resistance (r ohms). And Power lose = current squared (i come the twoth power) time resistance (R).

When you draw too much existing through a thin wire, due to the fact that its not a superconductor, you"re converting electrical energy into heat energy from Ohm"s resistive loss, leading to less electric energy (a voltage drop) getting to your load (appliance, light bulb, stereo, ...). The excess warm in the wire and also inside your wall causes the insulation to fail over time, creating a potential quick circuit accompanied by sparks that ignite flammables.

Have a licensed and also insured electrician (Journeyman or Master) or electrical contractor add a brand-new 20 amp circuit, or replace the currently 14 AWG cabling v 12 AWG cabling, or use your hair dryer in the bathroom i beg your pardon should already have a GFCI per NEC 210.8(A)1) and 20 amp receptacle every NEC 210.11(C)3) set up within three feet that the edge of a container per NEC article 200, section III forced Outlets, 210.52 apartment Unit Receptacle Outlets, (D) Bathroom.

When it gets cold I put on secondary non-electric blanket, long thermal underwear, a hat and also scarf, and also let the dog sleep on the bed through me.

During the winter you can want to end up being a "snow bird" and also fly southern to Florida rather of having actually to attend to electricity, aka "Organized Lighting" according to George Carlin.
