You will need to use #8 wire.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
For a 400W metal halide bulb, you will typically need a 14-gauge wire and a 20-amp breaker. However, it is recommended to consult the bulb's manufacturer specifications to ensure the correct wire size and breaker are used for safety and efficiency.
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.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.

For a 50 amp breaker, you would typically need a 6-gauge wire.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
Yes, you can.
You will need to use #8 wire.
8 AWG is typical.
The recommended wire size for a 50 amp breaker is typically 6-gauge wire.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
It is not the number of bulbs that you worry about. It is the wire size that is your concern. If the circuit is wired with AWG 12/2 wire then use a 20 amp breaker. If it is wired with a AWG 14/2 wire then use a 15 amp breaker. You are protecting the wiring with the correct size breaker.
The recommended wire size for a 20 amp breaker is typically 12-gauge wire.
The appropriate wire size for a 25 amp breaker is typically 10 gauge wire.
