I live in a complex apartment. My electrical panel at the main counter in the basement used to be a Buss fuse 30A time delay type and there is also a Buss type panel of 20 and 15A in my apartment. I am running a plasma TV + Receiver, 2 AC (8000 & 6000 BTU), 3 Tower fan , Desktop PC, Light. The consumption is respectively 6.3A, 7A, 5,5A, .6A X3, 2A, .3A and measured by Kill a watt P4400 Model. I turn off the 6000 BTU when using the Microwave 12A. In the summer time, the fuse blows couple of time every now and then. So I was mentioned the situation to the super intendant. He called an electrician and change all the panels to circuit breaker type of 30A at the main panel, 20 and 15A at the secondary panel. Since then, I am unable to use all my equipment as before. The cutting point of the 30A circuit breaker seems to be around 20.6A or so. So I have to turn off the PC and one of the fan to avoid the circuit breaker trip. As soon as I turn on the 3rd fan, the circuit breaker trip. And to use the microwave I have to turn off both AC.
I've call the building manager many time to fix the problem to no avail. He said that I have too much electronic / electrical device in my home but can't explain why I can't use the same load as before.
Can someone please explain:
- With the same rating, how can a fuse type handle the load and not the circuit breaker?
- Why the circuit breaker trip well below the 30A rating?
- Is there other circuit breaker (brand & model) that can handle similar load as the Buss fuse?
- Since the manager play the deaf ear, can I replace the circuit breaker back to a Buss fuse socket type? If so, where can I find such socket?
- If I can't replace the circuit breaker, can I call either an electrician or the electricity company technician to do it?
- I saw other electrical panel adjacent to mine and they seems to have twice as thick circuit breaker. Will I solve my problem if I mount the same type?
Any advice to resolve my dilemma would be greatly appreciated.
