Install a 50 amp breaker in the 100 amp panel and run appropriate size wire to the sub panel connectors...
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

ReneTo install a 50A sub-panel to a 100A main panel, you will need to first ensure that the main panel has enough capacity to support the additional sub-panel. Next, you will need to run appropriate gauge wires from the main panel to the sub-panel, and install a double-pole 50A breaker in the main panel to feed the sub-panel. Finally, connect the wires to the appropriate terminals in the sub-panel and ensure everything is properly grounded. It's recommended to consult a licensed electrician for safety and compliance with local electrical codes.

Adding a sub panel is a complicated job in as much as you have to know wire sizes, ampacity of wires and proper electrical workmanship. Such a project should be left to a licensed electrical contractor to take out the proper permits and call for proper inspections. By taking this route it will leave you confident that if any mishaps happen to the installation down the road your insurance company will be behind you 100%.
In an average home a 100 amp panel can used up to 55 amps at any one time during certain periods through out the day. There is a way to extend the bus with conductors of the same size as the distribution panel's bus bars. Discuss this option with your electrical contractor.
If you opt for a panel change, have a 200 Amp 42 circuit board installed. The labour costs are about the same as a smaller board, just the material costs are higher.

how do you know how to properly size a sub panel?
example:
100 Amp service panel is full...I understand that I will never use the FLA full load amp
rating of this panel but i want to be able to accurately size the sub because i am going to install a hot tub that requires a 50 amp breaker...
You put two 50Abreakers in the 100Apanel and feed each subpanel with conductors from one 50A or the other (i.e., two hot conductors, a neutral and a grounding conductor). There are specific rules about whether the subpanel may need its own grounding rod connection as well, depending upon whether it's in the same building, among other things.
You may optionally place another 50A breaker in each subpanel as a "main disconnect" for circuits fed from that subpanel.

My seimans elect panel box let me put in tandem breakers?
I wnt to install a tandem breaker but my panel box won't let me. Why?
Can a outlet box be mounted to electrical panel?
No, an outlet box cannot be mounted directly to an electrical panel. Electrical panels have specific requirements for clearance and access, and mounting an outlet box to it would violate those safety guidelines. It is recommended to install outlets separately on the wall near the panel if needed.
What are the required for electrical panel?
The main items required for an electrical panel include the panel box itself, fuses, and wiring. The wires are fed into the box and attached to a series of circuit breakers to allow electricity to be directed as needed.
Can you upgrade a 100A main circuit breaker to a higher amp?
Yes, it is possible to upgrade a 100A main circuit breaker to a higher amp rating, but it must be done by a qualified electrician following local electrical codes and regulations. The electrical panel and wiring may also need to be upgraded to accommodate the higher amperage.
How much does it cost to install distribution panel box with 20 circuit breaker space?
The cost to install a distribution panel box with 20 circuit breaker spaces can range from $500 to $1,500, depending on the complexity of the installation, the quality of the panel, and the labor costs in your area. It's recommended to get quotes from licensed electricians to get an accurate estimate for your specific situation.
