Example of fine electrical wiring practices. Use of extension cords.

Wenatchee Home Inspection Services.


Extension cords should be used only on a temporary basis! Correct?

Often during a home inspection I will see them used for much more than this.

The NEC in section 400.8 states “Uses Not Permitted” for flexible cords and cables.  


·        As a substitute for the fixed wiring of a structure.  


·        Where run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings, or floors.


·        There run through doorways, windows, or similar openings.


·        Where attached to building surfaces .The Start- Extension cord used as branch circuit






Here was particularly creative version of this practice of improper extension cord use.



Here is the cord as it exits the building.

Garden hose conduit in tree




Now we have that run that goes from one structure to the next using the old garden hose conduit system, a very fine variation of electrical conduit (look closely as it runs through the tree).






Next... of course running through a metal building adds to the beauty of this installation.

But when using such good practices we must be sure to terminate in a proper fashion as demonstrated here.

Sometimes you wonder how someone does not get hurt.

We see this kind of thing more often than you think. These cords get hot after a while and it's nothing but a fire hazard. People must think it wont "happen to me"?

Yikes!  I helped a buyer with a home where the inspector discovered an extension cord was used to power the jets in the master bath tub.  And there was no GFI around. It had likely been like that since the home was built but it was an accident waiting to happen.

"Common Sense" fixes are not always the best.

This only proves the value of an electrician.

Fernando, I agree. An electrician can save a lot expenses later.

 

Richie, Ya think ; ) This home was grand experiment on how not to wire a home.

 

Gary, This was one of those special places ; )

Charlie, darn tooting!

Anthony, very true.

Chris and Dick, That is why we have rule on receptacle placement to prevent the over use of extension cords.

Carmen, most extension cords have light gauge wiring that is not intended for this use, hence the heat.

Kathryn, That is a great use, and no GFCI to boot, Well done there : 0

 

Brian, very very true.

Donald,

This is a disaster waiting to happen. The sad thing is that this may not be the only illegal installation in the house. Sooner or later, that metal building will become live as wind moves that overhead back and forth. Do I notice unenclosed connections on the other side of that stud in photo #1?

Donald -- what creative work this fellow has done to get his power to the out building -- but I thought he would need a female connection, not a male connection at that end.  HMMM?!

Looking where that extension cord ends up is a maze of confusion, looks like a potential hazard.

Donald, People like this ar causing us all to pay more for fire insurance. I think a home inspection should always be required before an in suranse policy is issued.

Kate, Thank you.

Kevin, That one was one of the better examples I have found.

Adrian, You are welcome, got to love the creative use of materials.

Brad, True time will not be good on this installation.

Steve, You got it, that was the special termination along with the splice ; )

Lyn, The best part I was informed he was a contractor...hmm

Eileen, It was an interesting configuration.

Jim, Silly me, you are right it was properly protected from physical damage ; )

Wayne, Though I think everyone should have a home inspection, that would be a tough one to get going. It should be part of everyone's due diligence.

Donald, I see this type of thing quite often, espeially when some DIY electrician decides that it's time to wire up his shed. It really doesn't cost much extra to do it properly in terms of buying the correct wiring, but I guess people just naturally like to cut corners.

Temporary wiring can mean different things to different people I guess.
