when I plug-in a typical heating pad or a hair dryer into any type of bedroom duplex, the lights dim; and/or trips the circuit breaker. The house is of new construction-- inserted in business 31 Dec 2013. My inquiry is: can I safely replace the existing 15 AMP Breaker v that the a 20 AMP? . . . The service cable is that 14 Gauge Copper Conductor.

No!

The just safe method to rise the circuit"s volume 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: Replace 15 amp breaker with 20 amp

If you simply replace the breaker, the wire can overheat and ignite the building from inside the walls.

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

Absolutely NOT.

National Fire Protection firm (NFPA) typical Number 70, National electrical Code (NEC), embraced by most states (exceptions space Missouri, Mississippi and Arizona), needs the branch circuit Over existing Protection device (OCPD --typically a circuit breaker (CB) nowadays, quite than a fuse indigenous days of yore) to safeguard the cable/wiring hidden 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 home was not constructed to take care of heating blankets and also hair dryers in the bedroom. Swapping the end a 20 amp breaker for the 15 amp breaker will certainly violate NEC 210.19(A)(1) and provide cause for your insurance company not to reimburse her losses indigenous fire & smoke damage and also the water damages from the fire room flooding your house.

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

15 amp rated circuit breakers usage 14 AWG current carrying conductors (black warm & white neutral) + a eco-friendly ground wire which typically carries no existing in market standard outer white non-metallic sheathed cable referred to as NM-B 90 level Centigrade rated "Romex".

20 amp rated circuit breakers use the very same configuration yet 12 AWG, which is a bigger diameter wire 보다 14 AWG, and therefor has less resistance for the same distance/footage from the fill center/panelboard circuit breakers. 12 AWG NM-B sheathing is fancy yellow.

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

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

When you attract too much present through a slim wire, since its no a superconductor, you"re converting electric energy into heat energy from Ohm"s resistive loss, causing less electric energy (a voltage drop) reaching your load (appliance, irradiate bulb, stereo, ...). The excess warmth in the wire and inside your wall causes the insulation to fail over time, creating a potential quick circuit add by sparks the ignite flammables.

Have a licensed and insured electrician (Journeyman or Master) or electric contractor include a brand-new 20 amp circuit, or change the existing 14 AWG cabling v 12 AWG cabling, or usage 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) mounted within three feet the the sheet of a basin per NEC article 200, ar III forced Outlets, 210.52 populated Unit Receptacle Outlets, (D) Bathroom.

When it it s okay cold I put on an additional non-electric blanket, long thermal underwear, a hat and also scarf, and also let the dog sleep on 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 actually to resolve electricity, aka "Organized Lighting" follow to George Carlin.
