Sylvania breakers


heh KB Sparky
I bought a house with Sylvania's and the 220 circuits are not clipped together
Did they use and external clip or have a rod thru the hole in the breaker handle?
are there in comparable pins that will work on these breakers to clip them together

Sylvania breakers


You have 240V circuits that use two single-pole breakers instead of a double pole? The only solution for that is to get double pole breakers. Handle ties are not a substitute, since 240V loads require a breaker with an internal common-trip. Handle ties don't do that.

Sylvania breakers


Just out of curiosity, do your breakers look like this ?

Its a Zinsco breaker, but a lot of people have made them including Sylvania.
In my area, the big boxes and hardware stores carry the tandems, but not the common trips. I have to drive about 20 miles to get them from an electrical supply house. So, I have run into a lot of them with nails thru the handles.

It' not right, but a lot of people have done that.

I did cut an 8pd nail down to fit in the hole when I first noticed them missing, but it didn't look kosher
.looks like when it trips it will take both rockers out though.
I have a box full of Zinsco's

Sylvania breakers


Zinsco was bought by GTE in 1973 which they later renamed Sylvania, as they later sold off their electrical equipment div. that line was discontinued they were then renamed Challenger, who continued to make replacement breakers, they were bought & sold a couple more times & no longer exist but a company called UBI makes ChiCom sourced replacements*, Zinsco / Sylvania is one of the two most reviled names in electrical equipment, Federal Pacific Electric, FPE is the other.

* I would rather use old Zinsco then use ChiCom breakers, but that is just my opinion, the best thing to do is get rid of them as they have been obsolete for somewhere around 30 years give or take, and were used because they were cheap, one reason that you see them in a lot of tract homes & multi-family buildings, depending on what part of the US one is in.

Not all 240V loads require a two pole common trip breaker.

Read 210.4(C) 2008 or 2011.

If you elect to use multi-wire branch circuits (be sure to see the Code definition), then you need to meet the requirements of 210.4(B) which, at a minimum, requires the use of handle ties on SP breakers employed with MWBC.is a 220 application a MWBC?
Just wondering about DP breakers .if one side ''trips'' on double pole with out the handle clip ,does that close the circuit on both sides automaticlly?
Never realized yall had so much verbage to wade thru to wire a house .
It looks like the NEC is just trying to cover thei behind with multiple ways to interpret what they require

Sylvania breakers


Branch Circuit, Multiwire. A branch circuit that consists of two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor of the circuit and that is connected to the neutral or grounded conductor of the system.
So my 220 oven circuit ,that has a neutral and a ground would be a MWBC?

No, it would not be considered a MWBC, but would require a 2-pole breaker.
What do your breakers look like? If they are typical 1" style breakers Cutler Hammer BR series would be an acceptable replacement if a handle tie cannot be found. They are pretty cheap.

Is it wrong to reply to your own thread?

thank you. I will get them replaced with the BR's.
When the electrician comes out it is cheaper if you can spec out everything that needs to be done(only 1 trip charge)
