Most harmonic problems occur when the loads are not linear device (transformers). You'll need to have special equipment and qualified persons to check harmonic problems. If the load is found to be 80% or less, there may be an issue of harmonics that is causing the tripping. You need an amprobe or ammeter for amp readings. This is only an example to show how a certain circuit breaker might trip under a load less than the rating stamped on the body or handle.Ī circuit breaker that trips with no load or a load equal to or less than 80% of its rating is most likely defective. You only have 80 days to circumnavigate the globe. This is called "duty factor" or "service factor" The greater the load is in excess of 80%, the less time that the breaker will carry it before tripping.Īn example of a 100 amp breaker with different loads on it (this 100 amp value was chosen for ease of doing the math): Circuit breakers that carry more than 80% of their load will trip - if the load remains connected long enough. Likewise a circuit breaker carrying up to 80% of of the current it is rated for shouldn't trip either. You say there is no load on the breaker - how are you making this determination? Are you using an amprobe or some other meter?Ī circuit breaker with NO load shouldn't ever trip. You only have to exceed 50 amps on one phase to trip a 100 amp main.Ī tripping circuit breaker is an indication of an overload. If you have a significant part of the load that is not 220V, then it you might have a higher load on one phase than the other, and could possibly be remedied by switching phases on some of the branch circuits. On the other hand, if you can calculate or measure the total load and you aren't near 100 Amps, then you just need to replace the main. Travel back in time to the late 19th century and get ready for spectacular adventures on land, sea and air. #Free no download new around the world in 80 days games upgradeIf you are close to the rated load, then replacing the main will buy you some time (but probably not as much as the original because the bus bar connection to the main is probably slightly corroded too) but it won't solve the problem - you will need to upgrade to a higher amp service. The cleanliness and tightness of connections is critical to carrying loads at rated capacity. If it seems that the loading conditions have not changed from prior years, then you have probably been close to the 100 amp level before and a small amount of corrosion has occurred over time (accelerated by the heavy loading). ![]() Any plan switch after redemption of this offer will result in forfeiture of the discount pricing.This may sound obvious, but either the main breaker is acting normally because the load is near 100 amps, or it's defective.
