Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit.
15 amps = AWG # 14 wire with 15 amp breaker
20 amps = AWG # 12 wire with 20 amp breaker
30 amps = AWG # 10 wire with 30 amp breaker
40 amps = AWG # 8 wire with 40 amp breaker
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire. The wire gauge and breaker size need to match the specific requirements of the new heater to ensure safety and proper function. You will need to upgrade the wiring to accommodate the 10 2 wire needed for the 5000-watt 240-volt heater.
There should be two outputs on the 30 A breaker. You will need 10 AWG wire with 3-conductors and ground. Typically the wire colors will be Black, Red, White and (Green or bare). Connect black to one output of breaker and red to other output. Connect white to the white buss bar in main panel and green/bare to ground buss bar. At heater end connect the red and black to the 240 V leads, white to white and green/bare to the heater case.
It depends on how much electricity you plan to use in your garage. If you only need one or two lights and three or four outlets that will be used to power a vacuum or a single power tool, you probably only need a 15 amp circuit breaker. If you plan to run more than one tool simultaneously or if you have a freezer or something else that draws a lot of power on a continuous basis, you would be better off putting your heavy draw appliances on a separate 15 amp circut or getting a 20-30 amp circuit breaker.
For a 2500 watt water heater operating at 120 volts, you would need a 20 amp breaker. This ensures the breaker can handle the load without tripping.
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
To answer this question the voltage of the immersion heater is needed. I = W/E.

Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.

20 amp
The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.

To run a 500 watt 240 volt heater, you would need a 2.08 amp breaker. This can be calculated by dividing the wattage by the voltage (500W / 240V = 2.08A). You would typically round up to the nearest standard breaker size, which in this case would be a 3 amp breaker.
Usually 30 amp
