Hello,I have two separate loads,feeding (temporaliy),from one gfci feed.20a..there is 250ft of 14/2,,and a few outdoor lights. 800w of lights.The second load is 150ft,14/2 and 300w of lights. When I plug both in,I trip the gfci,not the breaker,,I have a CLAMP METER,can I go on a hot wire for each individual load,when on,and try to determine the amp draw??thanks,each of these loads work OK by themselves.
