does anyone know if they make a lay-in distribution block that i can use to splice 5 wires ranging from 300mcm to #3? I don't want to use an NSI splice block or a split bolt.I think the distribution blocks will be a neater job.With a big enough trough,I can install them in a row so I don't block them with other wires.When I say lay-in I'm referring to lugs like you'd have in a meter base.Thanks.
