I was gonna do a tap for solar on a old rusted out 800 amp switch gear. Main disconnect broke. It’s unfixable, what I want to do is put a non fused 800 amp service disconnect and tap into the existing 800 amp fuses. Existing switch gear is inside building on outside wall I want to put new service disconnect directly behind existing switch gear. It’s a brick wall. I would not think I would need a fused disconnect what do u guys think. Fused or non fused PACO is pg&e
New service disconnect

On 800 amp 1st thing I would check is the ShortCircuitAmpsAvailable vs the AIC rating of the switch. Most, if not all, NF disconnects have a 10K AIC rfating and qt 800 amps your SCA might exceed that rating.

If the disconnect is outside and the fuses are inside, I would see that as a violation of 230.91.
