View Full Version : 2- 20 amp breakers used for 220?

Ran into unfamiliar territory today - GE 200 Amp Panel that had 2-20 amp breakers with their levers joined by what appeared to be a flimsy copper rod of some sort that controlled a 110v style 220 receptacle - 3 prong with one flat and one horizontal slot. If the top breaker was switched off, the receptacle was still live but power was diminished. If the lower breaker was shut off, the receptacle was dead. The copper rod between the levers was not strong enough to flip both breakers off at the same time. Was this configuration a homeowner deluxe :eek: or something common and allowed? :) I've heard of using one leg of a 30 amp for 110v power, but not this. All help is appreciated - Jim. :D

Yes - that is the deluxe version of the homeowner "handle tie". :D

Nope, no way, no how.:)

The handle tie needs to be a listed device.

I called out this same configuration in a panel about 5+ years ago as being wrong. The electrician who did it called me and said it is considered acceptable. Ooookay. So I asked him if he would want this same setup in his own house. He said no.

Mmm hmmm.

Mmm hmmm. Ah yes, the "ole double-standard" - What's good enough for you, ain't good enough for me syndrome. Thanks Nick !!!:)

The handle tie is allowed on a multi-wire branch circuit where the loads are line to neutral only. If the load is 240 volt only or 120/240 the breaker HAS to be a 2 pole type.

2008 NEC 240.15 Ungrounded Conductors.
(A) Overcurrent Device Required. A fuse or an overcurrent
trip unit of a circuit breaker shall be connected in
series with each ungrounded conductor. A combination of a
current transformer and overcurrent relay shall be considered
equivalent to an overcurrent trip unit.
FPN: For motor circuits, see Parts III, IV, V, and XI of
Article 430.
(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), and (B)(3).

(1) Multiwire Branch Circuit. Except where limited by
210.4(B), individual single-pole circuit breakers, with or
without 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.
(2) Grounded Single-Phase and 3-Wire dc Circuits. In
grounded systems, individual single-pole circuit breakers
with identified handle ties shall be permitted as the protection
for each ungrounded conductor for line-to-line connected
loads for single-phase circuits or 3-wire, directcurrent
circuits.
(3) 3-Phase and 2-Phase Systems. For line-to-line loads
in 4-wire, 3-phase systems or 5-wire, 2-phase systems having
a grounded neutral point and no conductor operating at
a voltage greater than permitted in 210.6, individual singlepole
circuit breakers with identified handle ties shall be
permitted as the protection for each ungrounded conductor.

None of the exceptions apply here.

Handle ties force turning off both poles manually but the breakers can trip individually, there is no AUTOMATIC opening of both poles. That requires a 2 pole breaker.
