Not to mention the neutrals mixed with grounds under the same lug.

I don’t like the idea of locating the surge protector there because of the difficult of future serviceing. And how about the copper/aluminum connection?

The instructions for a surge suppressor says it is supposed to be connected through a breaker.


It can be a branch circuit breaker, like the one to the dryer but it has to be on the load side of the service dissconect

I bump in to this weekly on older structures with smaller original service panel breaker capacities. Owner doesn’t have room to add a sub panel breaker, so they boot leg wiring direct to a smaller sub panel adjacent to the main. Call the electrician. icon_idea.gif

You can legally splice a service conductor but that is not by double tapping the main breaker and the conductor should be sized to the disconnect.


If someone used a legal splicing method, bonding bushings on the raceway and service rated equipment for the second panel it would be legal (also made up as a “main” AKA service disconnect).


You can have up to 6 of these. This is not the type of thing amateurs should be trying.
