When I plug-in a traditional 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-- put in business 31 Dec 2013. My question is: Can I safely replace the existing 15 AMP Breaker with that of a 20 AMP? . . . the company cable is of 14 Gauge Copper Conductor.

No!

The only safe way to increase the circuit"s capacity is by replacing the wire via one of sufficient gauge. For 20 amps, 12 AWG copper is adequate for approximately around 100 feet.

If you simply rearea the breaker, the wire deserve to overheat and ignite the structure from inside the wall surfaces.

To resolve the dimming problem, examine that the outlet is in good problem and that the wires are secucount fastened and also not showing any kind of indicators of overheating: blackening or loss of the copper shininess. Also, check the end of the wire inside the company panel, both neutral and also "hot" (black) wire. If those are okay, set the appliances to a reduced wattage establishing or relocation them with lower wattage models.

Absolutely NOT.

National Fire Protection Agency (NFPA) Standard Number 70, National Electric Code (NEC), adopted by a lot of says (exceptions are Missouri, Mississippi and Arizona), needs the branch circuit Over Current Protection Device (OCPD --generally a circuit breaker (CB) nowadays, fairly than a fusage from days of yore) to defend the cable/wiring hidden in your walls from overheating by de-energizing (shut off/open circuit) all outallows (lighting & receptacles) for that circuit by tripping/blowing.

Lights dimming and also CBs popping is a certain sign your residence was not developed to manage heating blankets and also hair dryers in the bedroom. Swapping out a 20 amp breaker for the 15 amp breaker will violate NEC 210.19(A)(1) and also carry out reason for your insurance agency not to reimburse your losses from fire & smoke damage and the water damage from the fire department flooding your house.

Wire is made smaller when made by drawing/stretching it. The even more times its stretched the smaller sized it gets. This is why Amerihave the right to Wire Gauge (AWG) seems backwards, i.e. 14AWG has a smaller sized diameter than 10AWG bereason it was stretched even more.

15 amp rated circuit breakers use 14 AWG current delivering conductors (black warm & white neutral) + a green ground wire which commonly carries no existing in sector traditional external white non-metallic sheathed cable referred to as NM-B 90 level Centigrade rated "Romex".

20 amp rated circuit breakers usage the same configuration yet 12 AWG, which is a larger diameter wire than 14 AWG, and therefor has actually much less resistance for the exact same distance/footage from the load center/panelboard circuit breakers. 12 AWG NM-B sheathing is colored yellow.

10 AWG via orange sheathing would certainly be even much better electrically, however even more expensive and not compelled by "code", the NEC.

Blame all this mumbo jumbo on Physics and also a Gerguy called Georg Simon Ohm that created a Law that even Donald J. Trump can not repeal. Voltage loss (V) = current (i amps) times resistance (r ohms). And Power loss = present squared (i to the twoth power) times resistance (R).

When you draw also a lot existing with a skinny wire, because its not a superconductor, you"re converting electrical energy into heat power from Ohm"s resistive loss, causing less electrical energy (a voltage drop) getting to your load (appliance, light bulb, stereo, ...). The excess heat in the wire and inside your wall causes the insulation to fail over time, creating a potential brief circuit accompanied by sparks that ignite flammables.

Have a licensed and insured electrician (Journeyman or Master) or electrical contractor include a brand-new 20 amp circuit, or relocation the existing 14 AWG cabling with 12 AWG cabling, or use your hair dryer in the bathroom which need to currently have actually a GFCI per NEC 210.8(A)1) and also 20 amp receptacle per NEC 210.11(C)3) mounted within 3 feet of the edge of a basin per NEC Message 200, Section III Required Outlets, 210.52 Dwelling Unit Receptacle Outallows, (D) Bathroom.

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

During the winter you can desire to end up being a "snow bird" and fly south to Florida instead of having to resolve electrical energy, aka "Organized Lighting" according to George Carlin.
