american dj power bar circuit breaker tripping

Hmmm, I was wondering about this, I have some heated auto-water units for our horses and they seem to be tripping the breaker fairly easily this year. The guy at HD said no wouldn't happen

Overtime that strip will wear out and become weaker from tripping, or using the breaker as an on/off switch.

Floor staff in any store are not reliable sources for advice, the people that install and use the product or service on a daily basis are the ones who will know best. Regarding your horses, it might be the GFCI tripping. Please tell me those heaters are on GFCIs hehe anything and everything todo with water and livestock should be on GFCIs, its a no brainer.
