Hi everyone,I recently bought a house. One of the DIY things I want to do is replace all the light switches to rocker style and all the outlets since they have yellowed over the years. The problem I have now is determining 15-amp vs 20-amps. I am a complete noob at this and my knowledge is only based on things I have read on google. The things I know to be true are below.Outlets with the horizontal line are automatically 20-amps20-amp receptacles/switches can be used on a 15-amp circuit/breaker??? (but NOT vice versa). The reason people don't freely use 20-amp receptacles/switches is because they are super expensive.The breaker "may" show how much amp it is14G wiring to be used on a 15amp receptacle/switch (while 12G wiring on a 20amp) but that seems to be not 100% true based on what I read so I'm not sure if I want to go this route to help me determine.So my questions are...Any other tips on determining amps for receptacles and switches?If worst comes to worst, would buying all 20-amp items be cheaper than hiring an electrician to determine for me which is 15amp and which is 20amp? I assume they would want to install it for me and such.This is a follow up to question #2. Any risks in using 20-amp items that I am unaware of? I haven't found anything on the web.Is it possible for a house to have only ALL 15 amp circuits/breakers and NO 20 amps? If not, which areas of the house would I expect to see 20 amps? I live in a 1800 sq foot house, so not that big.Thank you all for your time and help. Please let me know if I'm wrong on anything. via /r/DIY https://ift.tt/2IwrdFh
