Until just recently my christmas decorations would light up when we plugged them into the outdoor electrical outlet. Now when we plug it in the gfci outlet in the garage keeps getting tripped and the lights won't come on. Even when we reset the gfci, once we plug in the chord it gets tripped again.. what should I do? Thanks

If the GFI only trips with the xmas lights plugged in, then there is a problem in the sting of lights and need to be replaced.

If the hot wire of the string, has a path to electrical ground it will trip. If several strings, separate and see if it reveals string touching "Ground".

Thank you for your responses. Will give suggestions a try and let you know what happens... thx again!
