Boy this is on every home inspection of mine for the last 3 years it seems.

Adding an electric line to an existing circuit breaker with possible overload.

In my former profession it stood for one to the body and one to the head...  Does that count? 

Lyn Sims and Wayne Martin have the correct answer.

As for my take it should be on a keg to cut down the line for a beer!

You have sparked my interest once again!

It's why they put two notches on the edge of each breaker, so that you can give it a double purpose.

But the inspectors do not like this so it is best to just use one notch and go buy another breaker for any expansions in your system.

It's what I do with my 9mm when a mugger tries anything with me or my family!

Raymond E. Camp beat me to this one. TGIF!

Tapping twice can create an overheated situation that needs attention for safety reasons!

When you absolutely, positively need to make sure the zombie is dead!

In murder stories, it means that you shoot twice.

Greetings,

A "Double Tap" is two wires / two different electrical circuits to one breaker that is not rated for two wires. Normally an easy fix for an electrician.

Here's a link to the explanation and a photo of it.  Hope this helps!

You are building a home and get frustrated. Off to the tavern and ask for a double tap. One will not do.

A dance in the breaker box.

When it's real hot out, is it when you fill 2 glasses at the same time with your favorite cold drink.

Overloaded breakers.

That is when the tenant does not pay rent and tells you they will not pay rent until repairs have been completed. Double Tap--

I know this one.

My definition and yours will lie at opposite ends of the spectrum I believe.

Tony and Suzanne Marriott, Associate Brokers Lyn Sims has this one.

when two wires are connected to a breaker that is set up for ONE wire...

A school drop out got into re biz by boasting he "double tap" on every deal.

It is a term used when talking about electrical wires that piggyback onto another circuit. This usually isn't a good practice.

A fire hazard!

I like Lyn Sims have been seeing this on several inspection reports for my buyers! It's adding an electric line to an existing circuit breaker and can cause overloading!

Tony and Suzanne Marriott, Associate Brokers - my inspector always finds one - specially one with the door bell and says it's okay...

I guess to make double income?
