Next Studspace Installation

If you don't already have your meter installed, go to the meter installation page.

First, a note on what is meant by "next studspace". The term "next studspace" as I use it here can really be interpreted as "next available stud space". What this means is the next open stud bay, of large enough size (a standard panel requires 14 1/2”), beside your meter cabinet. There are limitations on this concept, however, as the general idea is to keep your panel(s) as close to the meter as possible therefore keeping the amount of un-fused service cable inside the wall to a minimum. It is not acceptable, for instance, to mount your panel on the other side of a window or doorway from your meter. It is generally acceptable to skip a small stud bay that is not large enough to fit the panel. If you were using a 320 Amp service, you would generally mount one panel on each side of the meter cabinet. The final determination on this will be made by your electrical inspector so if you think it might be questionable, it would be prudent to contact him or her with a question before proceeding.

Find panel mounting height

There is no minimum height for your electrical panel. There is a maximum. The maximum height is determined by the height of the top-most circuit breaker. The center of the handle (in the up position, if an up-down breaker) must not be above 6'7" from grade or floor. That does not mean you have to set it that high! I usually set my panels at about 6' to the top of the panel. Your only limit is the maximum height stated above.

Remove the Screw Knockouts

Knock out the 4 little slot shaped knockouts from the sides of the panel if you are flush mounting your panel, these are the holes you will drive screws through to secure it to the studs

Mount the panel(s)

Hold your panel at the proper height and screw it into or onto the wall. Keep in mind that if you are flush mounting your panel, you need to leave the front of the panel out of the face of the wall enough to make it flush with the wall covering material.

Install the SE cable

Get an SE cable connector of the proper size for your cable. For each 200 Amp panel you will use 4/0-4/0-2/0 SE cable. Remove the proper size knockout from the top or bottom of the panel(s) and install the SE connector (I usually find it easier to bottom-feed my panels, if the panel can be mounted with the main breaker down, it just makes it easier later when the circuits are installed). Install the SE cable through the connector and secure the clamp, be sure to leave plenty of SE cable so you can reach the main breaker and neutral connection with the conductors. Now, using another SE connector, install the other end of the SE cable into the meter cabinet and connect the conductors to the loadside.
