Most building codes call for 12 guage wire for receptacles and 14 guage (smaller) wire for lighting.
To be legal, you must check your local building or electrical code, often available at the public library.
There is no designation of "sun room" in the National Electrical Code. Unless a receptacle is in an area designated in Article 210.52 (B) as one requiring a 20-amp small appliance branch circuit, it is only required that receptacles be on a 15-amp circuit with 14 gauge wire. These 20-amp "small appliance" areas correspond to recognized food preparation and consumption areas: kitchen, dining room, breakfast room, pantry, or similar.
Certainly, it is important to comply with local codes. However, people who conduct the trade on a regular basis need to continually compare their practices with existing and new codes to maintain compliance. The idea that a complete novice could digest and accurately apply the complexities of the National Electrical Code after glancing through a copy at the library is absurd, which is why many municipalities do not allow electrical installations by anyone but a licensed professional.

If you have an electrical outlet that has 2 prongs you have a room heater which has 3 prongs - you have attached a 2 prong adapter however after a while the adapter melts Should you buy a new one?
What should be done in this situation is to change out the two blade receptacle to a three blade receptacle. Depending on how old the house wiring is, will depend on whether there is a ground wire in the two wire cable that the house was wired with. It sounds like the old two blade receptacle is worn out and it is the looseness between it and the adapter that is causing the problem. A room heater can be about 1500 watts and that adjusts to 12.5 amps that is heating up and melting your adapter. A new three blade receptacle will be tighter and it will not heat up. If there is a ground wire in the back of the receptacle's junction box attach it to the new receptacle. If there isn't a ground wire in the junction box, replace the receptacle anyhow, it will be much safer that the set up that you have now.
Can you use a 20 amp receptacle for a 20 amp appliance?
Yes you can as long as it is feed off of a 20 amp circuit in at least #12 gauge wire.
Can you connect a 14 gauge nmb 2 wire to a 14 gauge nmb 3 wire?
Most local codes require that when extending or adding circuits, the circuit must be brought up to national code standards. This would necessitate that if you have a 2 wire circuit and are adding to it, that you rewire the entire circuit to 3 wires. However, in actual practice, it is common to see 3 wire nmb connected to 2 wire nmb without full re-wiring. It is important to note that when this happens, the ground wire in the 3 wire cable serves no purpose. You end up with what looks like a 3 wire grounding configuration at a receptacle or other outlet when in actuality you have no equipment ground. This allows a hazard to exist that no longer conforms to current code, and if someone were to be injured you may be held liable.
Is 8 gauge weld wire fencing stronger than 10 gauge wire?
Wire gauges are defined in such a way that the lower the gauge, the thicker the wire. So, 8 gauge wire is thicker than 10 gauge wire.

Which one of the folling types of wire can be used with the pressure terminals of a duplex receptacle?
The types of wire you can use on duplex receptacle with pressure terminal are labeled on the receptacle, next to the holes. AWG 14 and AWG 12 are the typical wire gauges used in this application.

How big is 6 gauge wire?
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
Is 8 gauge weld wire fencing stronger than 10 gauge wire?
Wire gauges are defined in such a way that the lower the gauge, the thicker the wire. So, 8 gauge wire is thicker than 10 gauge wire.
Can you use one length of 3-wire cable to provide electricity to 2 separate circuits?
In countries that use a single phase split secondary service you can. In modern homes this is the type of circuitry that is used for kitchen split receptacles. On the receptacle the tie bar is removed from the "hot" side of the receptacle. A red wire of the three wire cable is placed on the upper terminal of the receptacle. A black wire of the three wire cable is placed on the lower terminal of the receptacle. The white wire is placed on the opposite side of the receptacle under the silver coloured screw. This will give you a full 15 amps capacity on the top portion of the receptacle and a full 15 amp capacity on the bottom half of the receptacle.
What gauge wire do I need to run 250' to an outdoor gfci receptacle?
This is a voltage drop question. To answer this type of question a circuit voltage and the circuit load amperage must be given to calculate an answer.

How do you install 220 receptacle with white black and bare wires?
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
Is a 6 gauge wire larger than a 12 gauge wire?
Yes, the smaller gauge number, the larger the wire is.
Can you splice a small length of 16 gauge wire to 18 gauge wire for a repair?
Yes, you splice a small length of 16 gauge wire to 18 gauge wire for a repair.
