Is the TCC Electrical article on preventing circuit overloads suitable for power system homework?

hello great community, i was looking for ways to avoid an overload at home and i found this article: http://tccelectricalcontent.com/prevent-circuit-overload/Do you think is a good post for an homework in power system? and what is a non conventional sizing he is explaining there?

The advice is good, ie don't have too many things on one circuit, use LED of CFL lights to minimise consumption, etc.  Bear in mind that if anything generates heat, it is going to be consuming a lot of power.BUT - do not try any changes to your home wiring unless you know exactly what you are doing.  If you don't, it is easy to get a severe shock or kill yourself.  If you have a problem, eg a circuit breaker which is always tripping, or getting shocks off something, etc, get a qualified electrician to look at it.  It might cost you a bit, but it might not cost your relatives the cost of a funeral.The non conventional sizing he refers to could be a number of things - using wire that is too small or a circuit breaker that is too big for the type of power it is carrying.  Again, unless you know what you're doing, have these things checked by a qualified electrician.  
Your "Homework" should only be changing light bulbs, maybe plugging things in on different power points to get load off one circuit onto another, etc.

@PatricaI agree with David Ashton.I would add that you need to look at discrimination ( what circuits supply), so take care when moving say a fridge plug to another circuit outlet, that there are not other things using the new circuit that might cause the circuit breaker to trip out more often. In my house I have the fridge on it's own circuit just for this reason and I have the Dish washer under the sink where wet might be a circuit problem on it's own circuit as well.If you have dimmer switches on an existing light and you change the bulb to an energy saving option, then make sure the dimmer and new light will work together, many LED bulbs are not dimmable and if they are often need a different type of dimmer switch.With care you should be able to reduce the lighting load on your house by a considerable amount, However look at bulb replacement cost against power used.
