Attempting to use an appliance rated for 10A on a 5A electrical board using "trick means" is not recommended and can be extremely dangerous. Overloading the electrical circuit can lead to electrical fires, damage to the appliance, and pose serious risks to your safety and the safety of others.
Electrical appliances are designed with specific power ratings to ensure safe operation within a certain electrical capacity. Using an appliance with a higher power rating than the circuit can handle can cause the circuit to overload, potentially leading to electrical hazards and damage to the circuitry.
If your electrical board is rated for 5A, it means it is designed to handle a maximum load of 5 amperes safely. Attempting to draw more current by using "trick means" can result in overheating, melting of wires, electrical fires, or even electrical shock.
If you need to use an appliance with a higher power rating, you should consider having a qualified electrician upgrade the electrical circuit to handle the increased load safely. Upgrading the circuit involves rewiring and possibly changing the circuit breaker to one with a higher ampere rating.
Remember, electrical safety should never be compromised, and it is essential to follow the manufacturer's guidelines and electrical codes to prevent accidents and ensure the safe operation of electrical appliances. If in doubt, always consult a qualified electrician for proper guidance and installation.
