Double Tap at Service Disconnect

[DCInspector]

200 amp service to residential property. Property has 200 amp fused disconnect box feeding main panel. The load side of the service disconnect box is double tapped and feeding a sub-panel. I'm pretty sure this is an illegal double tap. Correct? With that being said, should the neutral and grounding wires be connected to the same bus bar in the sub-panel?

In my opinion these are not designed for double tap.
The neutral and the grounding have to be separated at the sub panel. However, are you sure that is not the service panel? I think it is.

To start:
(a) Assuming the fused disconnect is your first means of disconnect, any panels it feeds would be sub-panels and the grounding and grounded (neutral) should be separated,
(b) You would need equipment grounding conductors from the fusible to those panels (a metallic conduit would suffice if
properly installeed)
(c) obvious color code violation
(d) doubtful the lugs are rated for the two taps.
(e) the panels would need a main unless they are 200 amp rated and fed with 200 amp conductors.

Thanks.....this is the main panel, which is a very old Stab-lok panel!

What do you mean by (C)?

What do you mean by (C)?

The white wires connected to the hot leads in the disconnect?

A couple of suggestions :

1. See if you can find double lugs and change the lugs in either the fused disconnect or the larger main lug panel. If you install them in the main lug panel you'll have to install new wiring to the other sub panel
2. If not, see if you can convert any of the stab-lock breakers to the thin ones, thereby freeing up 2 spaces and then feed the smaller panel with a 2-pole breaker
3. If you choose to go with item # 1 then in item (c) of dc_inspectors post either change the color of the wires to black or color them with a magic marker. If you choose to go with item # 2 then you'll obviously have to run new wiring
4. Finally, in both sub panels the neutrals have to float and not bonded to the enclosures.
