Hello all,
I am doing a conversion in a house where it is being split into two apartments.
I am installing a double meterbase. Main lugs are 200Amp. Two subpanels will be 100 Amp each.
Do I need to ground the meterbase? If I do, with #2?
Do I ground the neutral and the grounding together in the neutral lug?
Do I also ground the panels to the water pipe?
Thank you for your assistance

I usually just ground the meterbase itself,then run a #6 bond wire from the meterbase to each panel. Remove the bonding screws in the panels and you are all set. The main ground can be #6 as well.

Why remove the bonding screws in the panels? I saw no mention of a main before the panels...

Because the neutral can only be grounded in 1 location, in this case the meterbase. Therefore the neutrals in the 2 panels must be floating,but the panels must be grounded back to the meterbase neutral with a #6 bond wire.
