crappy change over job

hidden1

Who ever changed out this did a crappy job,im still unsure where it links up.They had converted it from a 50 amp reg(electric) stove to gas and linked 3 20 amp outlets -12 gauge- and a light in on 50 amp .then 2 15 amp breakers -lighting- below it.Stove(gas now) must be on its own also.I guess ill have t devote it to stove only and change out 50 to 20as long as wire size is 12? Wanted to have over stove microwave on it also -same outlet.Any info is appreciated

Is that also aluminum wiring?

yep and hot!

do they pigtail off these to get to outlet also ?

I never knew you could turn 2 single poles into a double just by putting a NAIL through the breaker arm!
Lol.

Yeah, it's SEU cable. What's wrong with that?

When the handle tie rule came into affect on mwbc's you couldnt find handle ties for every manufacturer. I had an inspector tell me to just put a nail through them to pass.

A double pole breaker is not the same as two single poles with a handle tie, though. Double pole breakers have an internal common-trip mechanism so if one side trips the other side does, too. Handle ties are allowed for MWBC's with no 240V loads, but any 240V loads require a double pole breaker. Most inspectors require UL listed handle ties, but it is technically at their discretion whether to allow a nail or not. I've seen it inspected and approved.

Whew just when you think you have seen the worst--old style wire #6 linked to smaller 12 copper-linked -all off that that 50amp with 1 light and 3 outlets too..and ground was used with neutral.even open wire set aside...whew will have to replace with a 20 amp breaker and run new 12 wire to a new 20 amp or use a Al/Cu #6 split bolt(made to join the different type wiring) maybe?what a mess.

Code05

Incorrect.

210.4(C) Line-to-Neutral Loads. Multiwire branch circuits
shall supply only line-to-neutral loads.
Exception No. 1: A multiwire branch circuit that supplies
only one utilization equipment.

mpoulton

That provision allows a MWBC to supply a 240V load under that circumstance (e.g. a 120/240V dryer or stove), but it does not override the requirement in 240.15(B) that the OCPD open all poles automatically:

(B) Circuit Breaker as Overcurrent Device. Circuit
breakers shall open all ungrounded conductors of the circuit
both manually and automatically unless otherwise permitted
in 240.15(B)(1), (B)(2), (B)(3), and (B)(4).

Paragraph 1 under that creates an exception allowing handle ties for MWBC's that supply no 2-pole loads:

(1) Multiwire Branch Circuits. Individual single-pole circuit
breakers, with identified handle ties, shall be permitted
as the protection for each ungrounded conductor of multiwire
branch circuits that serve only single-phase line-to neutral
loads.
