so quick question i have a 1500w 120v element controlled by a pid with a computer fan on the same circut.now my question is is if i hooked a march 809 pump to the same circut would i pop my 15 amp breaker. i have 50' of 14awg
That long cord length resistance will also reduce the elements current reducing your 1500 watts heating element to a lower available wattage output. Feel the cord after 15 minutes running, bet it will be warm to the touch. I would do a dry run with water first.The 50' of 14 awg just adds resistance to the circuit which will reduce the amount of current flowing and therefore will reduce the likelihood of the breaker popping.
