The recommended wire size for a 40A circuit is typically 8-gauge wire.
Probably...The 6V 40A relay figures out as 240Watts...The same relay at 12V 30A figures out as 360Watts.

It will depend on how big the circuit is if its a 20a no if its 40a yes!
No, unless it's a gas range. An electric range requires 240V and 40A while a small appliance will be 120V and Max 15A.
A 40A MCB is a circuit breaker. The surge current limit is protected to 250A 8/s0uS. The limitation capability of a circuit breaker is that characteristic whereby a current less then the prospective fault current is allowed to flow under short circuit conditions.

Please call an electrician before you burn your house down! Changing a 40A breaker to a 50A breaker will eventually melt your wire's insulation and start a fire if it continues to trip. I would say you should change it back, but you should let the electrician do that. There is a short or overload in that circuit, which needs to be corrected before you attempt to reapply power. Circuit breakers are not there to make your life harder, they are there to make your life longer! Have a professional electrician correct the short or overload and then replace the breaker with a properly rated breaker before energizing the A/C unit.
