The apt size of a hammer that can be used a s a jigsaw would be
16oz.
Step-by-step explanation:
To see the size of hammer that would be necessary we must understand the size of the outlet box and how it would require the jig to be.
The average height of an outlet box is usually 12 inches from the floor and it is then attached to a secondary box above it which is 16 inches
So, to lift this piece by the jig we can see that the standard sized hammer of 16 ounces would be apt and would do the job completely well.
So this is the one that must be used.
