Should You Install 15amp or 20amp Receptacles, Grounding Ungrounded Receptacles, Circuits for AC Units and Lengthening the Wiring in a Chandelier

Don Kispert asks:
I am installing GFI receptacles in my bathroom and kitchen. Should I use a receptacle rated at 15 amps or 20 amps?
You are permitted to use 15 amp rated receptacles in the kitchen and bathroom.
So I cannot put a three prong outlet in place of the two prong,and run a ground to a nearby heating duct? I am only doing this to keep a recently purchased UPS quiet when it detects a “building wiring fault”.
No! If there is a fault on the line your ground wire will carry the current. This means that all of your duct work will be live including the metal grates in each room. I wrote a post a while ago about this. Click on the link below to read this article.
My question is aim going to install 2 wall unit a/c units one in bedroom and the 2 one in the living room can use 30 amp breaker for for both units or dedicate a 20 amp for each unit?
I would install a dedicated 20 amp circuit for each unit. You may only need a 15 amp circuit. Look at the unit to determine what the load is. The manufacturer should also have instructions and electrical requirements for each unit.
Can I lengthen wiring in a chandelier if I’ve cut it too short?
Yes you may. I wrote an article about this subject which includes step-by-step instructions. Please click on the link below to read this article.
