Why does the breaker in the main panel flip before the breaker in the spa box?

the problem is between these two breakers or you have a faulty or oversized breaker closest to the spa.

The breaker in the main panel typically flips first because it is designed to protect the entire electrical system of the house. The breaker in the spa box is typically more localized to protect the specific spa equipment and wiring, so it may have a higher tolerance before it trips.

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?
To determine the amps of a breaker box, look at the main breaker or label inside the panel. The number on the main breaker indicates the maximum amperage that the breaker box can handle. Make sure not to exceed this amperage to prevent electrical hazards.
How do you find out how big your main breaker box is?
You can determine the size of your main breaker box by looking at the number of circuits it can handle. A typical residential main breaker box is usually 100 amps, 150 amps, or 200 amps. You can also check the label on your breaker box or consult with an electrician for assistance.
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.

Is it OK to have 250 A of breakers in a 100 A panel?
Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.
What is a sub panel?
A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.More informationA sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box"."Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".
Where is the proper location for a main breaker in a panel?
Normally the main is on the top but you can install a service panel with the main on the bottom unless local codes prohibit it.

Can you put a breaker panel in a hall?
Yes a breaker panel can be located in a hall. In fact a lot of apartments have them in that location just as you come in the main door to the apartment.
I have a Transformer 480 primary 208 secondary feeding 1 200amp mb 42 space panel I need to feed a subpanel 6 ft away I'm thinkin feed through lug at top of bus or at feed through MB suggestions?
The sub-panel need to be fed from the main panel, by way of a circuit breaker connected to one of the breaker locations. Or if your sub-panel has a main breaker installed you can feed from the main panel with a sub-feed lug kit. This looks like a breaker, but is only a point where you can branch off the sub panel.
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.
What is the minimum size breaker panel for a home's main service?
50 amps
