Can I replace a 15 amp breaker with a 20 amp breaker?

How many breakers are allowed in a 200 amp panel?
The number of circuits and breakers you can install in an electrical panel is limited by the panel’s design. Most 200 amp panels will have 40 breaker slots but can accept more circuits with tandem breakers. 120v single-pole breakers will use 1 breaker slot, while 240v double-pole breakers will use 2 breaker slots.
What is the maximum number of circuit breakers in a panel?
The number of breakers can max out to 30-42, too, depending on the design of your 100-amp pane. However, NEC prohibits more than 42 circuits, so you can only choose between 20-42 breakers for a 100-amp panel. Breakers or circuit breakers act as a switch for cutting off power from the main electrical supply.
What can I use if I don’t have a main breaker?

What is the difference between a main panel and a sub panel?
The real difference between a subpanel and main panel is where the wires of system lead and the power of volts it provides.

Is a ground rod required for a sub panel?

Unless you plug an appliance into its slots, a 20 Amp receptacle on a 15 amp circuit is completely harmless.
Can a breaker be bad but not tripped?
