HelloRecently I installed 100W Bulbs in my home and noticed that the light fixtures became extremely hot and within 10 minutes they had started melting the insulation. So i looked at the wire and found that it was 18 Gauge and found that through all fixtures of the home some of them with at least 20 feet of wiring is this up to code? I also noticed that many sockets would not allow a laptop to charge or even a cell phone what could be the cause of this? I'm in ontario canada.
I believe that Ontario codes requires that NMD90 14 gauge wire be used.
It is typical for a 100W light bulb to become hot. The higher the wattage, the more heat is produced. That is why many electrical fixtures list the maximum wattage to be used with that fixture. I suggest you Google the Canadian Electrical Code to determine the proper wire gauge for your situation. The wiring standards in the US would be to use something more substantial than 18 gauge. You should measure the voltage at your outlets while you are trying to charge your computer. It sounds like you have excessive voltage drop from inadequate wiring. This could be a safety issue and might cause a fire. If you can't measure the voltage yourself, call in a pro. This is not something to put off!
On the fixture it self under the cover should be a sticker listing the max wattage of a bulb to use if its says say 60w max then you put a 100w in you answered your own question. Light fixtures are rated for wattage put to much in end result is over heated wires melted fixture and or a fire Buy a new one rated for a 100w most folks don't know they are rated hope that helps Lr
