Where do you source circuit breakers that are NOT in typical box stores? o Carling AA3-B0-24-635-5D1-C (do you have a decoder for that number?)



PG&E has currently cut the power to us in California where this is the 31st sustained power outage in three years (of more than a day each, generally), so my generator has been doing triple duty as the backup source of power.



Over time, this 35 amp ganged circuit breaker partially broke inside.

It has "Carling Switch" molded on one side:

And this barely readable paper label on the other side:

The best I can make out from that data are these specs: Carling Switch Inc. AA2-B0-24-635-5D1-C FL AMP 35 MAX VOLTS 227 (? hard to tell) HERTZ 50/60 DELAY 04 (? hard to tell) TRIP AMPS 43 (? hard to tell) Mexico 9513 (probably the 13th week in 1995, likely original)



I called Generac's 24/7 live hotline, but they can't give me any more information than the owners manual, parts diagram, and references 888-GENERAC (888-436-3722) extension 4, extension 2 1-262-544-4811 extension 1, extension 2, extension 4, extension 2



This is the relevant page out of that Generac Owners Manual they sent me:

o #5, Generac Part Number #74969, 35 Amp Circuit Breaker



Generac suggests these two outfits, who seem to charge astronomical prices: o $137.07

o $233.45

Hence, the basic question of how you source basic electrical parts.

We put them on the "f*ck you" list.

I bought a Honda 4500 watt generator 30 years ago. The only service it's required is the battery, the air filter and the oil.

As a friend of mine's brother-in-law succinctly put it, "Pay s*it, get s*it."

Arlen-

Take the old breaker into an Ace Hardware Store. You want something that has the same mounting and terminals, rated for 35 Amps and at least

240 Volts.

The 43 "TRIP" Amps would be nice, but is not the most important parameter. Hopefully you do not normally run the generator close to its limit.

I would not be surprised if Ace had the exact breaker for around $25.

Please ... go to HD, get a Square D breaker and rig it up. Duct tape if you have to <G>

The government should make it a law the companies have to sell to individuals the repair parts and service manuals if they have them.

Years ago I was with a friend at a boat warehouse picking up some parts. A man wanted to buy a simple part,but they would not sell it to him as he was not a dealer. We bought the part for the man and sold it to him at our cost when he met us outside the warehouse. Most places would have doubled the price to him.

What really hirts is if a big company buys lots of items at high dollars and the manufactor goes out of busniness and they will not give or sell you a manual on the equipment when you buy it.

Mouser or Newark - in stock for under $30

I think Team Amazon is teaching all those "wholesale only" assholes a painful lesson.

Make that Mouser. Newark price is WAY higherr and no longer in stock. Mouser has 10 in the warehouse

If you are in ANY business, technically you can buy wholesale. I can't buy anything that requires a gas fitter's licence or a refrigeration licence (actually I can from a few wholesalers) but if I show my businesscard I can buy pretty much anything else I might need through my company. Automotive, small engine, electrical, plumbing, electronics, building supplies - just about anything partly duer to the structure / nature of my business and the way it is stated on my card.

Thanks Clare for that purposefully helpful lookup, where I may have made an inadvertent typo at some point, as it's AA2 (2 pole), not AA3 (3 pole): o AA2-B0-24-635-5D1-C

Mouser doesn't stock this part, but they do have a decent datasheet:

I will need to call Mouser during business hours for price & availability: o (800) 346-6873, (817) 804-3888

Unfortunately, Newark also says "Not Normally Stocked":

formatting link

But at least they list a price, where, the going "fair" rate is about $100 o $ 92.45 onlinecomponents.com o $ 95.53 newark.com o $137.07 jackssmallengines.com o $233.45 ordertree.com

The question is mainly HOW do you guys get hard-to-find electrical parts.

BTW, the smoke is everywhere easily smelled, strongly in the air, with that classic wood burning smell, where the most recent time this happened was the Paradise Fire, where the smoke traveled hundreds of miles to blanket the Silicon Valley as this smoke is just now starting to do today with the picking up of the wind in the past few hours.

What "I" would do, in all likelihood, is CONVERT it to a standard more easily available part. Like a QOB. Just have to work out a mounting method.

Thanks for that purposefully helpful advice on considering this breaker: o Square D QOB235 2 Pole Circuit Breaker

It would be nice if the circuit breaker fits reasonably well in the front:

Where, in the rear, it's less important how things bolt together:

formatting link
Where the Carling uses four 10-32 terminal bolts (lug type).

I thank you for not trolling, since it takes zero energy for the trolls to troll while you went to the trouble to find a decent fit, where what I'll do is trace out a paper cutout on the generator and take it with me to Home Depot or Ace to see if the $30 "Square D QOB235 2 Pole Circuit Breaker" can be retrofitted into that front panel hole.

Thanks for spending energy to bring items of value to the Usenet potluck.

That is a very normal form factor for industrial equipment.

This thread is about how to source hard-to-find electrical parts.

Given results below, the summary is things "can" be sourced. o But there must be a better way to source hard-to-find parts. For those times you want the part in your hand today.

While converting to a different part, particularly from a part that clearly failed prior to its 10,000 cycle rating, often works, and, I've often Rube Goldberg'd myself, given this is an electrical component attached to the mains, and given it has to be "to code", and given that it can kick in when I'm not home, my FIRST CHOICE (for the minor price difference of $30 for a different part & $100 for the right part anyway), is to try to source the correct part that has bolt holes in it, rather than an alternative that doesn't fit the weathertight outdoor generator enclosure attached to a huge source of propane:

Anyway, this thread is really not about the part per se, but how to SOURCE hard-to-find electrical parts, which is more of a TECHNIQUE than anything else.

On technique, I learned a lot about phone calls in the past few hours...

Given those results, the summary is things "can" be sourced. o But there must be a better way to source hard-to-find parts. For those times you want the part in your hand today.

If you can live with a 30 or a 40, Grainger has them for $32. They might be able to order the 35 but you are out a few weeks I imagine. What do you have in the transfer equipment at the panel? If you have a

35 protecting it at the panel for overloads, a 40 will adequately protect the feeder for short circuit.

Look at "Panel, 6-32 mounting type"

If you want an uncommon part in your hand today, Rots of Ruck my friend. The only way around it is to "rube" a common part to fit or pay the exhorbitant prices charged by those who MAY have the part in stock because they "service" that particular device that needs the part.

The FACT that it is a "common industrial part" does not help the common man source one in an emergency.

That brings up another point though - were you not aware MONTHS ago that the genset was not functioning properly? I seem to remember you making a half-assed attempt at getting information about it WAYYYY back. The time to find out it needed that breaker , and sourcing it at leisure was THEN.

The generator has been running for 3 days now, where it quit sans warning earlier today, where a check of the 12VDC car battery showed it was down to

6 volts, so, obviously, the charging circuit wasn't working (there's a lot of corrosion on the battery terminals, but it starts up the generator just fine when it's at 12VDC).

I know the battery was fully charged as PG&E had given us a day's notice, so I had charged it for that day until the power went out 3 days ago.

The 8KWH generator has been burning propane at about 50 gallons a day (near as I can tell from the gauge on the propane tank, which isn't all that easy to read accurately), and where I used a jumper cable from a nearby vehicle to debug that it was the battery and then, once debugged, I swapped in a second car battery to keep the electricity going today (and put the dead battery on a charger):

Looking inside each of the two transfer panels, one for each half of the house, they seem to be listed as 100 Amp service each based on this wording on the outside of the Generac part number

Where there are 4 fuses in each of those two panels, all of which are supposed to be the "uniquely sized" 600 Volt 2 Amp Buss SBS-2 fast acting fuses, where it currently has 4 and 5 amp Buss BBS-4 and Buss BBS-5 600 Volt fast acting fuses (which came with the transfer panel when I bought it) but where the 2AMP SBS-2 fuses have a similar (but not as bad) sourcing problem as does the circuit breaker.

This is, I think, OEM but based only on Ebay listings, which may be wrong: o

This is original that the electrician originally put in the transfer panel: o

The house is 200 Amp service, where my understanding is that each half of the setup handles 100 Amps, but where I'm not sure why the original electrician put in 4amp and 5amp fuses when online, I see pictures of all sorts of sizes, but some of them are 2Amp fuses, so it's hard to tell what's the correct fuse amperage.

I don't see anything else inside the transfer panel that is fused.

Although the generator has the 35-amp circuit breaker & a fuse:
