When the core of the Sun/Star reaches about 10 million degrees Kelvin.
Nuclear fusion is the process that causes a star to begin producing vast amounts of energy by converting hydrogen into helium through a series of fusion reactions in its core.
The primary type of fusion that occurs in the red giant phase is helium fusion. As the star's core runs out of hydrogen fuel, it contracts and heats up to the point where helium fusion can begin, converting helium into carbon and oxygen. This process generates energy and causes the star to expand and become a red giant.
The core will reach between 250,000,000 to 500,000,000'C at its stable temperature. Beforehand it will rapidly gain heat from hundreds of thousands to its stable temperature, where it can begin the process of nuclear fusion. Hope that helps!
A fusion reactor stops in the main sequence stage when it runs out of hydrogen fuel at its core. As hydrogen is depleted, the fusion rate decreases, resulting in a decrease in energy production. At this point, the star will begin to expand and evolve into a different stage of its lifecycle.

During the main sequence of the star.
The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.
The minimum temperature is about 10,000,000 degrees Celsius.

No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
