What can a loosely connected electrical wire in a breaker panel cause?

A short, which will trip the main breaker.


What would happen if a 200 amp breaker is used in a 100 amp sub panel?

There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.


How do you read breaker box amps?

The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.


How do you find out how big your main breaker box is?

Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.


Can you daisy chain breaker panels?

No, breaker panels should not be daisy-chained as it can create a safety hazard and overload the system. Each breaker panel should have its own dedicated circuit from the main service panel.

Why would power be received before breaker but with breaker on no power is in any recepticles?

The voltage before the breaker is from the distribution panel's buss bars. This voltage is controlled by the panel's main breaker. To have no voltage on the terminal of the breaker means that either the breaker is shut off or it has gone into a trip position. If it has tripped push the handle of the breaker to the off position and then to the on position. This should reset the breaker. If the voltage is not present at the output terminal of the breaker after resetting it, then replace the breaker as it has a fault in it.
