No, you should match the breaker size to the wire gauge. A 10-2 wire is typically rated for a 30 amp breaker. Using a 20 amp breaker on 10-2 wire could result in overheating and a potential fire hazard.
In general, you should never use a breaker larger than 20 Amps on a #12 AWG (American Wire Gauge) copper wire.
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.
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
The wire sheathing itself is usually marked. e.g. 14 CU 2 or 14/2 CU will indicate 14 gauge 2-wire (+ ground) copper (CU being the symbol for copper on the periodic table). For 15amp circuits you will likely has 14 gauge wire with most of that being 14/2 (Usually white, black, and bare copper).
The recommended wire size for a 100 amp breaker is typically 2-gauge copper wire or 1/0-gauge aluminum wire.
The recommended wire size for an 80 amp breaker is typically 4 AWG (American Wire Gauge) for copper wire and 2 AWG for aluminum wire.
The recommended wire size for a 70 amp breaker is typically 4 AWG (American Wire Gauge) for copper wire and 2 AWG for aluminum wire.
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 size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
For a 100 amp breaker, a wire size of 2 AWG (American Wire Gauge) should be used to ensure proper electrical safety and performance.
No, you should match the breaker size to the wire gauge. A 10-2 wire is typically rated for a 30 amp breaker. Using a 20 amp breaker on 10-2 wire could result in overheating and a potential fire hazard.
The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
In general, you should never use a breaker larger than 20 Amps on a #12 AWG (American Wire Gauge) copper wire.

For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
