Old Pull Out Fuse Panelbd

[olc]

1. I assume these panelboard uses replaceable fuses - is this correct?
1b. If so is there a good reason to replace the panel with a new circuit breaker panelboard?

2. Is there a more official term for this type of panel?

The bottom 3 are 400A. I assume it is one per phase.

In commercial building zones, with equipment listed over 10K AIC, selecting fast fuses can reduce AIC & equipment damage. By comparison, in laboratory Short-Circuit tests, the fastest breakers result in equipment blown off walls and massive fire-balls engulfing the room.

In residential zones under 10k AIC fuse boxes that don't except modern AFCI's are usually replaced, but without knowing if those AFCI's will hold.

Keep it. There is nothing wrong with fuses. Panel also looks to be in good shape.

It is funny you say that. This panel is actually in a rectory (i.e. residential) ( and feeds the separate church). There is another smaller pull-out fuse panel. It only serves one receptacle circuit (hallway receptacles).

Not to go off on a tangent - but are you saying that using AFCI breakers on an existing receptacle circuit may be iffy? (I have seen a couple issues of this situation.)

Yes, read this thread

Thanks for the replies.

I think, in this case, the options are 1. don't replace, or 2. replace with circuit breaker panelboard.

You have listed NO GOOD REASON to replace this panel board.

Is there a good reason to replace that you have not told us?

+1 or 2 if you count the first reply.

3. Get permission for inspector determination & walk thru.

Changing that switch gear fuse box to breakers is despicable, and only keeps you busy for a day, but correcting the illegal extension cord's, missing exit signs, adding tamper-resistant outlets in the nursery, and extra outlets when extension cords are gone, will keep you busy for weeks.

I don't have any reason to replace it. I don't think it should be replaced. I just want to make sure I am not missing something.
