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.

What size breaker do use for tnia 10?
For a TNIA 10 (Thermal Magnetic Circuit Breaker), the appropriate breaker size would depend on the specific requirements and rating of the circuit it is protecting. The breaker size should be chosen to match the maximum current rating of the circuit it is installed on to ensure proper protection against overcurrent. It is recommended to consult the manufacturer's specifications and guidelines for selecting the correct breaker size for the TNIA 10.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time .

What is the purpose of a 20 amp double pole breaker in an electrical circuit?
The purpose of a 20 amp double pole breaker in an electrical circuit is to provide protection by simultaneously disconnecting both the hot and neutral wires in the circuit if there is an overload or short circuit, preventing damage to the circuit and reducing the risk of electrical fires.
Will changing circuit breakers in box for electric heat reduce heating bills?
No, all it will do is make the circuit unsafe if a larger breaker is installed or make the circuit trip unnecessarily if a smaller breaker is installed. You pay for the wattage that you use. Less wattage used, less cost on your utility bill.
What is the purpose of a 15 amp double pole breaker in an electrical circuit?

What is the difference between Draw-out and Fixed-air circuit breaker?
Draw-out and fixed-air circuit breakers are both types of circuit breakers used in electrical systems. The main difference between them is how they are installed and removed from the system. A draw-out circuit breaker can be easily removed from its housing for maintenance or replacement without disrupting the electrical connections. On the other hand, a fixed-air circuit breaker is permanently installed in the system and cannot be easily removed without disconnecting the electrical connections. Draw-out circuit breakers are commonly used in critical applications where downtime must be minimized, while fixed-air circuit breakers are more suitable for applications where frequent removal is not necessary.
