I'd recently been given an EMF meter and when I turned it on, the EMF around most of the house was around 15 head height. If I'm downstairs and raise it to the ceiling it's well above 100 and the same upstairs putting it towards the floor. Now this is a bit worrying as we've been living in this house for the last 16 years but not only that I've recently had kids and where my 3-year-old sleep's he's being pummelled with 20 gauss.
I'd turned all power off at the fuse and proceeded to remove fuses to narrow down which circuit was causing the high levels. My first thought was it must be the light circuit as it was the roof and floors that had the highest readings but it turns out it was the outlet circuit that's causing the issue.
I've done some research and found that a neutral wire returning via a different live wire can cause this to happen and is in fact quite a common issue.
So my question is where and how is it best to start to find where that neutral wire has gone astray?
I'm currently in the process of getting our old fuse box replaced with a newer version. So thought now would probably be a good time to look into getting this sorted. Thanks for your help in advance.
