once I plug-in a conventional heating pad or a hair dryer into any kind of bedroom duplex, the lamp dim; and/or trips the circuit breaker. The home is of new construction-- placed in service 31 Dec 2013. My concern is: can I safely replace the present 15 AMP Breaker with that the a 20 AMP? . . . The company cable is the 14 Gauge Copper Conductor.

No!

The only safe method to increase the circuit"s capacity is by instead of the wire with among adequate gauge. Because that 20 amps, 12 AWG copper is adequate for up to around 100 feet.

You are watching: Changing 15 amp to 20 amp breaker

If you simply replace the breaker, the wire have the right to overheat and ignite the structure from within the walls.

To settle the dimming issue, inspect that the outlet is in great condition and that the wires are securely fastened and not showing any type of signs the overheating: blackening or lose of the copper shininess. Also, inspect the finish of the wire within the company panel, both neutral and also "hot" (black) wire. If those are okay, collection the appliances come a lower wattage setting or replace them with reduced wattage models.

Absolutely NOT.

National Fire Protection firm (NFPA) standard Number 70, National electrical Code (NEC), adopted by most states (exceptions room Missouri, Mississippi and Arizona), requires the branch circuit Over current Protection device (OCPD --typically a circuit breaker (CB) nowadays, quite than a fuse from days the yore) to safeguard the cable/wiring hidden in your walls from overheating through de-energizing (shut off/open circuit) every outlets (lighting & receptacles) for the circuit through tripping/blowing.

Lights dimming and also CBs popping is a sure authorize your home was not built to take care of heating blankets and hair dryers in the bedroom. Swapping out a 20 amp breaker because that the 15 amp breaker will certainly violate NEC 210.19(A)(1) and carry out cause for her insurance firm not come reimburse your losses from fire & acting damage and also the water damage 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 cable Gauge (AWG) appears backwards, i.e. 14AWG has a smaller diameter 보다 10AWG because it was extended more.

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

20 amp rated circuit breakers usage the very same configuration but 12 AWG, i beg your pardon is a larger diameter wire 보다 14 AWG, and therefor has less resistance because that the exact same distance/footage native the pack center/panelboard circuit breakers. 12 AWG NM-B sheathing is colored yellow.

10 AWG with orange sheathing would be even better electrically, but much more expensive and also not forced by "code", the NEC.

Blame every this mumbo jumbo on Physics and also a German called Georg Simon Ohm who produced a law that also Donald J. Trump card can"t repeal. Voltage loss (V) = present (i amps) time resistance (r ohms). And also Power lose = existing squared (i to the twoth power) time resistance (R).

When you draw too much current through a thin wire, since its no a superconductor, you"re converting electrical energy into heat energy from Ohm"s resistive loss, leading to less electrical energy (a voltage drop) reaching your load (appliance, irradiate bulb, stereo, ...). The excess heat in the wire and also inside your wall causes the insulation to fail over time, developing a potential brief circuit attach by sparks the 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 present 14 AWG cabling through 12 AWG cabling, or usage your hair dryer in the bathroom i m sorry should currently have a GFCI every NEC 210.8(A)1) and also 20 amp receptacle per NEC 210.11(C)3) set up within three feet that the edge of a basin per NEC article 200, section III required Outlets, 210.52 populated Unit Receptacle Outlets, (D) Bathroom.

When it it s okay cold I put on second non-electric blanket, long thermal underwear, a hat and also scarf, and let the dog sleep top top the bed v me.

During the winter you could want to end up being a "snow bird" and fly southern to Florida rather of having to deal with electricity, aka "Organized Lighting" follow to George Carlin.
