Installing Meter base/disconnect on exterior wall, connecting to load center with 4/0,4/0,4/0,2/0 SER cable.

1/2 inch plywood wall. How do I connect cable to meter box? Just cut extra large hole to accommodate a standard cable clamp or is there a better alternative?

I am installing a meter/disconnect and connecting to a load center elsewhere in the house. Meter is surface mounted on exterior of home. 4/0,4/0,4/0,2/0 SER cable will go through back of meter into wall. Question is how to I attach cable to box? Just cut larger hole in wall board to accommodate large metal cable clamp or is there a better alternative?

I HAVE 200 amp service to our house, outside at the meter we have two 100 AMP Breakers below the meter, these are grounded with 4 ga wire to two grounding rods, 6 feet apart. There are two sets of underground wires coming into the house, each set goes to a separate breaker box. THESE BREAKER BOXES ARE NOT GROUNDED. Is grounding at the meter adequate or should the breaker boxes be grounded as well

Lee, it sounds like you have two main disconnects and two sub-panels, completely legal if the main disconnects are fed from one meter and the installation is done correctly. Basically the main disconnects outside would be installed and grounded just as you described. There would then be four conductors (two un-grounded, one neutral, and one ground, either in a cable or a conduit) going into the sub-panels inside. It would look something like my tutorial that starts here: http://wireyourownhouse.com/panel/subpanel1.html

I want to say thank you very much for sharing your knowledge!

I'd also like to ask if you (or your web maintenance person) might be able to add a "Back" or "Previous" button at the bottom of each page - if that is possible.

Thank you Angela! While I did program the website myself, I am no website guru. I'm sure there's an easy way to use some method and add a "Back" button to all the pages, but I don't know it offhand. I'll do some research and see what I can find out. The site was hand written and programmed, so it's not as simple as just telling a program to do it for me. If I have to manually add a code snippet to every page, that's a lot of work, as there are a ton of pages! Thank you for the suggestion though, and I'll look into it.
