electric line shows 100 volts instead of 122volts PLEASE HELP !

[alfedo]

Hello everyone,
one of the electric lines in my house suddenly began losing power, it shows only 100 volts instead of 122 like in other lines, as a result I can't use it and it's one of the main lines in my house. Can someone please give me an advise what I should do to fix it?
How can I find what causing power loss? I greatly appreciate any help
thank you in advance
Al

What are you on about you numpty, in England we use 230v!!!!!

I'm in USA :83:

Hi Alfredo, 99% of us here on this forum are UK based, but the principles remain the same so I'm sure we can give you some pointers.

So, are you saying that from most of the outlets in your house you've got 110+, but on certain other outlets in the same building they are much lower? Fed from the same switch board but on different circuits?

Lost neutral or earth?

Lost neutral or earth?

Either that or I was thinking an appliance gone faulty and dragging the line down (water heater or something else chunky)

Assuming of course that it's not a 3ph install!

 

[alfedo]

yes that's correct, and this (faulty) line was fine until a few days ago, I have tv connected to that outlet and also wall light went off along with tv so I guess they all feed from the same line

 

[Rockingit]

Have you done any work around the house? Drilled anything into the walls or like that?

 

[alfedo]

no work has been done around the house, and no other appliances connected to this line

Are there two or three lines plus neutral to your house? If outlets fed off one of the other lines are OK it’s unlikely to be a neutral fault. are you getting the same problems with 240V outlets?
Sorry for the questions but fault finding over the net isn’t the easiest.

A spark I worked with spent some time in Canada which is the same as the US all lights and low powered equipment is normally of 110v but when it comes to high powered equipment eg washing machines etc it is 230v with a shared neutral (weird way of wiring in my view)

First of all - you clearly not an electrician so call one out!

How are you messaging this? - if your using a multimeter - STOP and get the electrician to visit!

2nd - Have you done any building work recently?

3rd - what is the voltage between neutral and Earth

4th - what kind of earth do you have over there?

The reason why I asked the questions.
I've worded on a lot of 240V three phase systems.

I've gotten UK 230V kit to work in the States on more than one occasion (when someone's forgotten to order the transformers...) Just take two phases and use them as L & N, ignore the 3rd leg. Not perfect by a long way, but gets you out of a hole for a day! (And confuses the heck out of US sparkies!!!)

Dual voltage household installations are quite common in the states.
This was sent to me by a friend in NYS. He was quite proud of it, he’d just tidied it up! God knows what it was like before.
