Locate buried electric line?

[ultrarunner]

When we redid my brothers house 25 years ago I bought a contractor pack of GFCI from the Box Store...

Eventually had to replace all of the ones that were outside... some would not trip and others would not reset.

At the hospital we use Hubel... so I went with Hubel and no more problems.

It is easy to see why some have strong opinions based on experiences both ways.

I actually have a greenlee 501 tracker II, WORKS GREAT. Mind you it set me back about $700 bucks, but im always trying to locate underground wires.

But this system wont locate a break location. When i encounter a line break, i usually subcontract to an underground location company. They have $$$$$$$ system that can locate exact break location and tell its depth. Costs about $150 on average. Beats digging up 200 feet of trench to locate break.

Check with your local utilities ... around here we have a free locating service that will come and mark buried lines. When the guy comes to locate, If you ask nicely they will likely locate your buried line for you..at least give you a ball park locate

By policy most if not all utilities only service their wire/pipe. They will locate their stuff between the pole/curb & the house (always call 811 before digging) within 3 days. But they won't do your wire or pipes. Stuff out to your barn, shop or a light pole are on you. Sometimes the locater will be nice or can be bribed, but not always.

What brand do you use?

Never had a Hubel go bad...

Early 90's is when I was very active in the property rehab business... GFCI were part of every job... it is the only thing I ever got call backs on... nothing else.

I still have GFCI related calls for property management.

Almost always the GFCI is doing what it is supposed to do... but, that doesn't prevent me from losing several hours for time on each call... things like a bad cord on a vacuum or bad power strip and one that caused a lot of problems for me in lost time is a tenant owned defective washing machine... it would trip every time the water level on the washer was set to high... a few drops of water splashed out for lack of a better term... several service calls by me and also the appliance manufacturer...

Tenant ended up jamming a paper clip into the GFCI button so she could wash... I bet I had more than a day on this... plus the GFCI was replaced when nothing was wrong.

Also... I refuse to daisy chain GFCI... been that route in an apartment building... just way too much time spent where no time was ever spent before.

Take 2 welding rods or similar wires. bend them 3 inch from one end hold one in each hand like a water witcher search for the wires

It does work. A lot of buried phones have been located that way. We used coat hangars and when they cross you have found it. Try it first before dismissing it

Back in the old days (early 50s) using fingers was common. Guy I helped for awhile one winter had it down; one finger= 120V, 2 fingers same hand = 240V, 2 fingers same hand standing/kneeling on rubber pad= 480V. He could tell the voltage working down from 480 if it was unknown. He had calluses on his fingers 1/4" thick from twisting wires and pulling wire/cable. He warned "do not use both hands as it will go through your heart". I did not try it either, I already knew what it did to me. He was a crusty old guy in many ways. Learned a lot in the 4 months I worked with him, including bending 1" conduit by hand.

Some of my best times studying and partying were with these hilarious guys.

It was our old Army Nuclear Power Plant course but Jimmah Cahtah nixed it. But if your an alumn you knew all that!
Have a great weekend.
About the old crusty sparky using his fingers; yeah I forgot how calloused my Journeyman's fingers were!

My gfi were probably from HD. Have them in all required locations, baths, kitchen, garage, shed, basement.

Generally this says more about a lack of use than it does practical use experience...or a case of extreme good luck...

An Internet search will lead to failure rates of up to 57%...

Most are always used. Kitchen, basement garage, baths, shed. Most of these have load 24/7. The ones that dont get used much are outside.
