if it is left pluged in a person trying to turn the braker back on will wont able to do so with out it triping repedly after.
Step 1: Get the Plug
you will nead
a wire nut / heat shrink tubing or electrical tape is cheaper but will get hot if you use a plug with thin wire so i say use wire nut
a plug chrismass light plugs will not work aka any thang that has a fuss built in to it and would take more work to chang it so dont use them .
note any plug will do but if you want to trip by the gfci braker then you nead a 3 prong plug other wise i would use a 2 prong cheap easy to come by BUT THE 2 PRONG PLUG WILL MELT A LITTLE WITH A SPARK
