Why do resistors often have a safety factor of 2 in regard to their power rating?

That might be done if the resistor is in a restricted space where the air flow is limited.
You need heat sinks to keep the resistors from burning up. A long time ago, I used resistors "to specs", and they burned up in a week. So I used "10x specs", and they burned up in a month. Finally, I waterproofed the resisters and dumped them in a pail of water (a big heat sink) -- that worked. (Not to be recommended, however.)

Why is a resistor needed to discharge or charge a capacitor in an electric circuit?
A resistor may be used in series charging for current limiting, filtering, or as a signal isolater. Resistors across caps are to discharge them for your safety or equalize voltages across the caps in series filtering circuit.
Do you split wattage on 2 pole breaker?
If the load is rated 220 or 230 or 240 volts (all the same thing), and specifies a wattage rating, that wattage rating is at the double pole voltage. You wouldn't make any adjustments to it. The load should also indicate the input current in Amps, which is used for sizing your breaker. If not, watts=amps x volts, so amps=watts/volts. For example, a 3800 Watt heater at 240v would require 15.83 amps. The breaker for this circuit would be 125 percent of that (safety factor), or 20 amps, 2 pole.
