In order to safely and properly complete that electrical wiring project you must be able to choose and install the right size and type of cable. All electrical conductors are rated by how much current they can safely carry before overheating and possibly causing a fire. The amount of current that a wire can safely conduct is determined by its AWG size (american wire gauge). In the tutorial below I give a basic introduction to NEC table 310.16 which gives the maximum allowable ampacity for a specific size conductor.
If you have more questions on how to determine the right size wire for your job or the maximum size circuit breaker or fuse by all means leave a comment and I will get back to you as soon as possible. Well with all that said I hope you enjoy the presentation and just a side note, this is my first screencast so go easy on me 🙂
