ECN Forum Forums General Topics of the Trade General Discussion Area Breaker Lockouts

The one in Trumpy's picture looks like the ones I have that are made by Brady. They work okay for locking out a circuit temorarily to service it but, like any lock, they only deter lazy people. I've had folks cut these off with sidecuts before. In a workshop for mentally handicapped I used to do service for I had a 90 lb. "resident" break one of these off with his bare hand. It cost me a good set of Kleins, but fortunately nothing else.

What I was looking for is some personal preference regarding the lockouts or "lock-dogs".

For example, Panduit makes some solid looking lock-dogs that can quickly get pricey. Bradey makes some cheaper ones that look like they would be much more prone to break. Prinzing makes some cheap lock-dogs, but I've heard tell they work on so few styles of breakers so as to be almost useless.

Does anyone actually own a specific brand that they know works well?

Renosteinke, you mentioned you have a few different types. Do you have a preference?

RobbieD, how well do the Panduit devices actually work?

Most equipment I work with is new Square-D QO and Homeline. But hopefully I'll get into some service work where I could run into just about any style breaker out there.

Thanks for the responses so far.

For me, it's the proper tool for the proper job. Other than the one shown by Trumpy, I have never seen a universal one that I thought was worth the money.

I like the Square D QOHPL at $6.30 list it is inexpensive enough to have several in your tool kit. http://ecatalog.squared.com/fulldetail.cfm?partnumber=QOHPL

Oh what happened to the old days were you just shut off the breaker, open the panel, pull the wire out of it and stuck a wire nut on it? Close panel of course...

Mike,
Yes, that works for a lockout, but it does not work for the breakers where the NEC requires that they be capable of being locked out.

BigJohn, I like them and I think that work fine. I don't think that Panduit makes a lockout for mini-breakers though. There are all kinds of lockout devices out there. Get the measurements of the most common breakers that you work with and match them up to the correct lockout device. JBD's suggestion is good, maybe the best person to get the lockout device is from the manufacturer of the breaker. At least it will fit perfectly then. As for me I like red ones because they stand out and say "Someone is working on this" To each his own though.

e57,

A) I ain't old enough to remember those days.
B) I got tons of wire nuts, I want an excuse to buy some new tools.

To any who are interested, here's a helpful LOTO device review.

"I ain't old enough to remember those days."

I aint either...

Most of mine are from Ideal, purchased at my local supply house. The type pictured is the most commonly used one.

I also have a few from Panduit.

One of my customers has large valve-wheel lockouts for putting on the door of the electric room when we have the panel open. Not a bad idea.

If there is ANY doubt in my mind as to the LOTO being honored, I will also take the additional step or removing the wires from the breaker.

If someone who should know better removes or defeats a lock-out, I'm off that job site until said person becomes unemployed.

Square D has the worst most user unfriendly breaker locks I have ever seen. You have to shut off the breaker below the one you want to install or remove the lock from.
