1500 Amp Circuit Breaker

A 30a circuit breaker can safely carry the exact 30a current but nec suggests 80 as a safe current limit as compared to the rated current of cbs.

1500 amp circuit breaker. But if you put a single 100 watt lightbulb in the bathroom light fixture you create a situation where a tripped circuit breaker is likely. When a few lights or a television are on the same circuit the 15 amp limit is quickly reached and the breaker will trip. The eaton s dc and pvgard molded case circuit breakers are engineered to address the highest performance requirements while providing numerous accessories to fit different site specifications. As circuit breakers cbs and overcurrent protection devices ocpd are designed for 100 rated current i e.

A 1500 watt heater on a 120 volt circuit thus needs a breaker of 15 6 amps. A 1500 watt space heater on high setting will draw 12 5 amps. To protect the 1500w inverter i m told that i need to add a 225 to 250 amp circuit breaker between the inverter and battery. Grainger s got your back.

The likely maximum load on that circuit could reach 1 800 watts putting it right at the maximum that a 15 amp circuit providing 1 800 watts could handle. Because a 15 amp breaker would be too small you need a breaker with the next highest rating which is 20 amps. Today s dc circuit breakers have expanded applications including solar photovoltaics electric vehicle charging stations battery storage and ups systems as well as commercial and industrial dc. Looking for eaton molded case circuit breaker 600 a amps number of poles 3 series hmcp 46my51.

A 5000 watt 240 volt heater would need a dedicated 25 amp circuit breaker and a 10 gauge wire. Circuit breaker size calculation for continuous non contentious load. Then multiply the amperage by 0 8 to find 80 of the rated amperage. Instead of trudging up and down the stairs to reset the breaker or replace the fuse only to have it trip again the load on that circuit must be reduced.

Eaton s dc and pvgard molded case circuit breakers are engineered to address the highest performance requirements while providing numerous accessories to fit different site specifications. A 1500 watt 120 volt plug in heater would need a 15 amp circuit with 14 gauge wire for temporary use. Fuses are the cheapest option but i d prefer a circuit breaker solution if possible but the costs go up dramatically from what i can find. To quickly determine the amperage of a circuit breaker find the amperage marked on the handle of the circuit breaker.

For double pole breakers don t add the amperage of the two breakers together because they will still operate on the individual amperage labeled on the handles.
