**breakers**are designed to carry 100% of their rated current while the NEC dictates an

**80**% application.

Similarly, it is asked, do breakers trip at 80%?

a circuit ** breaker ** is designed to carry 100% of its current rating, but the nec rules limit the application for continuous loads to **80** % of the circuit ** breaker's ** rating.

One may also ask, what percentage does a breaker trip? In other words, the ** breaker ** controlling a circuit ** should ** be 125 ** percent ** of the continuous load (maximum current expected to last for three hours or more) and 100 ** percent ** of the non-continuous load (shorter bursts of power, such as that needed to start up).

In this regard, what does 80 rated breaker mean?

The ** rating ** will be higher for the standard, **80**%-** rated breakers ** because you need to allow for an extra 25% capacity on the continuous loads.

What is the maximum load on a 20 amp breaker?

Allowable ** Breaker Load ** The NEC does specify that a circuit ** breaker ** shouldn't handle more than 80 percent of the ** load ** for which it is rated unless the ** breaker ** is labeled otherwise. By this standard, the total current draw on a **20**-** amp ** circuit shouldn't exceed 16 ** amps **.
