Yes, you will need a panel and transformer to achieve isolated ground wiring for furniture power outlets.

Since the electrical panel (H1) does not have an isolated ground bar, you will need to create one. This can be done using a panel and transformer, which will isolate the ground wire from the neutral wire.

Procedure

1. Install a subpanel with an isolated ground bar. This subpanel will be used exclusively for the furniture power outlets.
2. Install a transformer between the subpanel and the electrical panel (H1). The transformer should be rated for the amperage requirements of the furniture power outlets.3. Connect the isolated ground wire from the furniture power outlets to the isolated ground bar in the subpanel.
4. Connect the neutral wire from the furniture power outlets to the neutral bar in the subpanel.5. Connect the ground wire from the transformer to the ground bar in the electrical panel (H1).This configuration will provide isolated ground wiring for the furniture power outlets, which is necessary for data transmission.

Note: Always consult with a qualified electrician to ensure that the installation is done correctly and safely. Follow all building codes and electrical regulations when performing electrical work. Flag for review
