The only safe method to rise the circuit"s capacity is by replacing the wire through one of adequate gauge. For 20 amps, 12 AWG copper is sufficient for up to around 100 feet.
You are watching: Can you change a 15 amp breaker to a 20 amp breaker
If you simply replace the breaker, the wire can overwarmth and also ignite the building from inside the wall surfaces.
To resolve the dimming worry, check that the outlet is in excellent condition and that the wires are secudepend fastened and not mirroring any type of signs of overheating: blackening or loss of the copper shininess. Also, inspect the end of the wire inside the business panel, both neutral and "hot" (black) wire. If those are okay, collection the appliances to a lower wattage setting or rearea them with lower wattage models.

National Fire Protection Agency (NFPA) Standard Number 70, National Electric Code (NEC), adopted by a lot of says (exceptions are Missouri, Mississippi and Arizona), calls for the branch circuit Over Current Protection Device (OCPD --frequently a circuit breaker (CB) nowadays, quite than a fuse from days of yore) to safeguard the cable/wiring hidden in your walls from overheating by de-energizing (shut off/open up circuit) all outlets (lighting & receptacles) for that circuit by tripping/blowing.
Lights dimming and CBs popping is a certain authorize your house was not developed to take care of heating blankets and hair dryers in the bedroom. Swapping out a 20 amp breaker for the 15 amp breaker will violate NEC 210.19(A)(1) and provide reason for your insurance company not to reimburse your losses from fire & smoke damages and the water damages from the fire department flooding your residence.
Wire is made smaller sized once manufactured by drawing/extending it. The even more times its extended the smaller sized it gets. This is why Amerihave the right to Wire Gauge (AWG) seems backwards, i.e. 14AWG has a smaller diameter than 10AWG because it was stretched more.
15 amp rated circuit breakers use 14 AWG present moving conductors (black warm & white neutral) + a green ground wire which commonly carries no existing in sector conventional outer white non-metallic sheathed cable referred to as NM-B 90 degree Centigrade rated "Romex".
20 amp rated circuit breakers usage the exact same configuration yet 12 AWG, which is a bigger diameter wire than 14 AWG, and therefor has actually less resistance for the very same distance/footage from the load center/panelboard circuit breakers. 12 AWG NM-B sheathing is colored yellow.
10 AWG with orange sheathing would be also much better electrically, however more expensive and also not compelled by "code", the NEC.
Blame all this mumbo jumbo on Physics and also a Germale named Georg Simon Ohm that produced a Law that even Donald J. Trump can not repeal. Voltage loss (V) = current (i amps) times resistance (r ohms). And Power loss = current squared (i to the twoth power) times resistance (R).
When you draw also a lot current through a skinny wire, since its not a superconductor, you"re converting electric energy into warmth power from Ohm"s resistive loss, leading to less electrical energy (a voltage drop) reaching your fill (appliance, light bulb, stereo, ...). The excess warmth in the wire and also inside your wall reasons the insulation to fail over time, producing a potential short circuit accompanied by sparks that ignite flammables.
Have a licensed and also insured electrician (Journeymale or Master) or electrical contractor add a new 20 amp circuit, or relocation the existing 14 AWG cabling through 12 AWG cabling, or usage your hair dryer in the bathroom which must currently have a GFCI per NEC 210.8(A)1) and 20 amp receptacle per NEC 210.11(C)3) installed within 3 feet of the edge of a basin per NEC Post 200, Section III Required Outallows, 210.52 Dwelling Unit Receptacle Outlets, (D) Bathroom.
When it gets cold I put on a secondary non-electrical blanket, long thermal underwear, a hat and scarf, and also let the dog sleep on the bed with me.

During the winter you could want to become a "snow bird" and also fly southern to Florida instead of having actually to resolve electricity, aka "Organized Lighting" according to George Carlin.
