I'm installing an ev charging station and need some help with it. I'm going to be installing a separate meter from edison with the installation. And can't get a clear answer from the utility on the installation on it. My customer is saying we need a line side tap to the new meter. But I have never had to install one like that before. Is there supposed to be a line side tap or do I just install a new beaker in the panel to the meter and ev charger? Please help.
