Title: Hi quality breakers
Post by: mikeeastman on 14 Dec 2017, 05:41 pm
I have dedicated circuits for my system, I had the sub panel and breakers cryoed but I would like to upgrade to a higher quality ac breaker, I'd prefer  a din rail breaker,  I found some made by Schneider Electric that look ok, anyone have any other recommendation?


  Thanks, Mike

Very interesting, I didn't know breakers could make a difference?? Have you been able to confirm this?

I have dedicated circuits to my audio room also, with 10ga cryo wire. I would be interested in upgraded breakers as well if it makes a difference.

What is a Din rail breaker?

Thanks........

A DIN rail breaker is for use in industrial products, it may not have approval for use in a residential system.

Never ever cryo a circuit breaker!!!
The breaker depends on spring tension and other metal properties. Cryo will most likely chance those properties.

You dont mentiopn if you will need 1,2 or 3 poles.
In my country the B curve circuit breakers are used to work w/electric showers, heaters, electric ovens and incandescent light bulbs.

The action C-curve circuit breakers run w/washing machines, electric motors in general, fluorescent lamps.

D-curve circuit breakers are used to networks with large loads, such as transformers.

There are 2 other safety circuit breakers types:
DR residual differential protects people or animals from electric shocks.

DPS Surge Protection Device serves to protect electronic equipment connected to the electrical circuit, seems suited to computer and CD Players.

Maybe hi Amp DPS be suited to big amps.

They are single pole breakers, 1-15 amp and 1-20amp. It seems logical that if the wire makes a difference than the breakers would also. I use din breakers, both A/C and D/C all the time in my solar installs and they meet all the codes. I'm just looking for the highest quality I can find.

Breakers are rated for safety not for sound quality, in this case you will have to relie in personal opinions and snake oil marketing talk.

  Siemens non magnetic breakers sound good to me. I believe they have silver contacts available.

In Europe, Schnneider residual current Super immune circuit breaker is a very good idea if you have a dedicated line to audio equipment => additional protection in front the harmonics at mains in polluted environments and networks.

Why?

The electricity network is getting dirtier every day. The widespread use of cheap SMPS, cheap electrical motors, air conditioners (they add DC at mains too)....  usually made in East Asia (China). And bad electrical installations in elevators, and...

With out a doubt they are safe and of high quality. But solar panel systems are more like industrial products than a residential main breaker box (panel board).

I got on the phone and contacted a couple of electrical tech guys and they both recommended the Sq D QOU breakers. One guy said he used to install high end systems in the Chicago area and he always used those breakers. I ordered some and will let you know what happen.

I have taken apart a couple different brand breaks in the past. I was looking at how I could improve them. Those I disassembled were made up of both non magnetic and magnetic metal parts. Not ideal IMO. I did cryo my breaker of the dedicated circuit. I think the best approach would be a old style screw in fuse or cartridge style fuse panel. The parts that matter are all no magnetic. Buss bars are copper. They might or might not meet code depending on location/rules and regulations?

I was thinking about using audiophile fuses, they make fairly decent fuse holder for car audio that will easily handle 20 amps+.

In the 1970s I rented a apto which had these fuses you mention, they had a ceramic body.

  Thanks, Mike

I see you live in the US.

Per NEC code only breakers specified by the manufacture of the electrical panel can be installed in the panel. Branch circuits breakers used are combination Thermal/Magnetic. 

What manufacture and type of sub panel did you have installed?

Copper bus or aluminum bus?

Square D QO uses plated copper bus in their load centers.

Cutler hammer also makes a load center that uses non plated copper bus. I think Siemens does as well.

Personally I like the Square D QO.

Stay away from load centers that use aluminum bus.

Square D Homeline brand has aluminum bus. Square D started making this residential panel many years ago to compete with other manufactures that use aluminum bus in their panels.

Interesting. You are the first person I know of that has posted on an audio forum that uses a breaker DIN Rail system to feed branch circuit wiring for an audio system.
Edit: I have read posts where someone was using an Isoclean electrical panel board. Which I should add is not approved for use in the US for its' represented intended use.
http://www.unitedhomeproducts.com/id171.htm

Square D QOU breakers.
http://www.starlinepower.com/wp-content/uploads/sites/5/2015/11/QOU.pdf

What type/manufacture breakers are you using now?

Did you build, assemble, your own electrical panel board?

How many branch circuit breakers are install in the electrical panel enclosure?

What type of aluminum enclosure did you use to house the breakers? Hinged front cover? Does the electrical panel enclosure have dead front?

How did you feed the Line side of the breakers?

What size of wire did you feed the sub panel with? Feeder (feed) breaker size?
120V only?

Sorry for all the question. Your post peaked my curiosity.

 Din rail breaker are commonly used in Europe and in solar system in the USA. I'm using SqD Homeline breakers and sub panel now, it has 2 circuits 1-15 amp and 1-20amp. The enclosure I plan to use is this https://www.solar-electric.com/baby-box.html. Or I thought I might try making one and line it with copper sheeting. Din breakers have wire connecters for both input and output so tho wire is connected directly to the breaker, which I feel gives a better connection than a plug in type breaker. I feed the sub panel with #6 cryoed wire, tied directly to my inverter and the dedicated circuits use #8 cryoed romex. As my power is supplied by inverter it only puts out 120v.

The DIN rail breaker are safe when installed for their intended use.
But a residential AC power system is not their intended use.
There are many rules and code articles about residential power systems.
All you can do is use top shelf products from a wholesale electrical supply store.

Note that any residential system update might require GFCI or AFCI breakers.
Title: Re: Hi quality breakers

Din breaker are used in solar systems for both D/C and A/C and meet all the codes. I purchased them from Graingers so the must meet code or they won't sell them. I got the recommendation for these breakers from the tech guy at a large wholesale   supply store. Also if your concerned about safety as I said my power is supplied by an inverter and in the 25 years I've never blown a breaker because the inverter shuts down quicker than the breaker can blow. The only exception to this in my experience is if there is a sub panel that is far from the inverter, but we're talking about 80'-100' feet. My sub panel is 3' from my inverter.
Title: Re: Hi quality breakers
Post by: Speedskater on 15 Dec 2017, 04:34 pm
Of course DIN rail breakers meet code for their intended use.
There are 1000 pages of NEC codes and a lot more UL codes.
Grainger carries them because they are used in industrial products.

For a sub panel used to feed branch circuits feeding an audio system I do not see an NEC code violation using Din rail breakers.

Providing,

The breakers are Listed for their intended use. Breakers are sized correctly for the branch wiring and rating of connected outlet/s. Therein receptacle outlet/s. 
Enclosure used to house the breakers is Listed.
A dead front is provided to protect the user from energized live parts.
The assembly and wiring of the electrical panel is done by a licensed electrician.

The problem with the Isoclean audio grade electrical panel system is it uses 32 amp breakers.  That does not meet NEC code if the breakers are supplying power to two or more 15 amp receptacles or a 20 amp receptacle. The maximum circuit breaker that can be used is 20 amp, per NEC. It doesn't matter if the branch circuit wiring is #12  or #10 wire or even larger.

I replace existing breakers ( Homeline ) in my dedicated sub panel with Din rail ones made by Schneider Electric. They've only been in for 5 days so they probably need more burn in, I also replace the wire going from my inverter to my dedicated sub panel. The  changes I've noticed so far is my bass has more punch also before if I played a blank track (one used to test floor noise in car audio) and turned the vol all the way up and laid my ear on my tweeter there was a slight bit of hash , now it's dead quiet. So at least to my ears different breakers makes a difference in SQ.

Yes the Schneider Electric breakers are much better than HomeLine.  But many people will have issues with NEC, UL and inspectors.

If they sound that much different, you must have corrected some problem along the way. If breakers burn-in, well then they trip.
