Back then the headlight circuit was protected by a circuit breaker that was built into the headlight switch.
There is no headlight relay. All the switching is done in the headlight switch including a circuit breaker.
The headlight circuit breaker is intergrated with the headlight switch.
If there are not "short's to ground", you probably have a faulty circuit breaker for the headlights.
For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.
For a TNIA 10 (Thermal Magnetic Circuit Breaker), the appropriate breaker size would depend on the specific requirements and rating of the circuit it is protecting. The breaker size should be chosen to match the maximum current rating of the circuit it is installed on to ensure proper protection against overcurrent. It is recommended to consult the manufacturer's specifications and guidelines for selecting the correct breaker size for the TNIA 10.
For a circuit with a load of 10 amps, a breaker of 15 amps should be used for adequate protection. It is important to choose a breaker size that is slightly higher than the load to prevent frequent tripping and ensure safety.
A 30 amp breaker wired with AWG #10 wire.
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
The minimum size equipment grounding conductor required by the NEC for a branch circuit protected by a 50-ampere rated circuit breaker is 10 AWG copper or 8 AWG aluminum.
The continuous current draw on a 20 amp circuit breaker should not exceed 16 amps to allow for a safety margin. This helps prevent overheating and potential tripping of the circuit breaker. It is important to follow the manufacturer's guidelines and not overload the circuit.
