Pictured is the electrical panel in my garage of the house we purchased some months ago. I added a single 220 breaker for my compressor and a vfd to as yet unbuilt dc with 3 phase motor. The power to both go to separate fused shut off boxes. I added the grounds to where the existing grounds and neutrals were. Now, I'm thinking maybe the neutrals and grounds should be seperated? There is a separate ground bar on the opposite side of the box. Just want to keep things safe although this has probably existed for many years. Thanks.
