As most of you know i do very little resi work but today i came accross in a attic j-box 5 neutrals and 5 neutrals spliced together with a single # 12 neutral as a jumper between the two. although properley rated for the 20 amp ccircut is this permissible? I am very concerned as this is the bosses license going on this job. I will talk to him tomorrow and the inspecction on our work is monday but you thoughts and comments are apprecciated . This is a 1950s prefab house which we did the service changeover & a new garage. I opened the box cause i found 3 romex cables going into one connector.A violation in itself. Eagle eyes with Bi-focals. Thanks gang. Always Steve
