If the laptop is already grounded with our USB grounding adapter (Either the Premium or the Ultimate), then anything you plug into the laptop via USB or HDMI or DisplayPort will also be grounded.  Many monitors/displays are grounded already - if they have a big thick 120 volt cable with 3 prongs that goes directly into the monitor - then it is definitely grounded.  If a monitor/display has an external AC/DC power adapter - a box or brick that plugs into the outlet, and just a thin cable that goes to the monitor (a DC power cable) then the monitor is NOT grounded.

So, if the monitor IS grounded...you have a choice.  You can ground your laptop through the monitor.  In this case you would no longer need to use our grounding adapter (except when you travel or are not hooked up to the monitor).  If you want to use the grounding adapter AND the monitor is ground itself, you could use one of these to isolate the ground so that you have not double-grounded and created what we call a "ground loop" which can be a chaotic and noisy thing.

We were unsuccessful to come up with a *great* solution to shield your own cords.  Using foil tape makes the cords very stiff and large unfortunately.  Although foil tape can be used with the conductive shiny-size out.  Then you can use our grounding cords here: https://www.electrahealth.com/Grounding-Cord-with-Outlet-Plug_p_174.html

You would need to strip off the insulation from the grounding cord *NOT* from the cord you are shielding of course!!!  So you start with the cord you want to shield, attach foil tape so the shiny conductive side is outward (pretty much the only way to do it).  AFTER you attach the foil tape then attach our grounding cord fully stripped.  Then tape over that with electric tape or 3:1 shrink tube.  Keep in mind that working with any electrical cords/plugs is a risk and we are not responsible for any damage to property or injury to person.  DO AT YOUR OWN RISK!

The grounding cord should retain/keep its insulation except for the portion that is contacting the foil-taped cord you wish to shield and is safely covered with electrical tape or shrink tube.  This will lower risk of creating a short or having an issue.

We have 8 foot 14-gauge shielded extension cords here: https://www.electrahealth.com/Extension-Cords_c_57.html

Those would be the best, as the 14 gauge is the largest size wire we carry and can handle the most current.  I think we do have *some* 8 foot 16 gauge left still.  For now we do not plan on continuing carrying the 16 gauge.  But 16 gauge is great for typical electronics and things.  If you want to plug high-draw items in, go with 14 gauge for sure.  We have 8 foot available - that is the shortest size.

I do not recommend using an unshielded cord since it will emit high electric fields.  We are the only company with machine-manufactured and UL listed shielded extension cords on the market.

The voltage readings seem erroneus, as AC wires in the home shouldn't be able to produce such high readings.  I suspect your meter is inaccurate.  Although, you may have high voltage lines nearby outside.  I would still prefer to take readings with a Gigahertz Solutions meter or alternatively with a "body voltage" meter.

This kind of thing can be shielded against with the YShield paint - having properly grounded the paint.  Many people prefer to ground the paint to an earth versus to the electrical power system.  There are risks doing this.  But there are also risks to electric fields being so high.  You can "mock" shield the room with standard aluminum foil and grounding the foil.  You can connect sheets of foil with conductive tape (we have this in stock - call to order).  Then you can "test" what it's like with the shield in place and grounded.  You can test with the meters and also with how you feel.  If you feel better - then paint the wall :)

We really like those peak numbers to be below 10 at all times.  Some people will even say 1.  The Building Biology recommended levels are 0.1 or below for peak.  I'd like to see average down below 1 really.  Peaks below 10.  There is no set number because some people can still become ill with very little exposure.  But yes, the readings you are getting are very high and are alarming.  You may consider shielding or using bed canopies, which we have had very good results with.

The BioInitiative Report and the Building Biology Institute are two good resources that discuss exposure levels and how they relate to research as well as other evidence - anecdotal evidence from countless individuals.

That is absolutely always preferable.  Truly 100% analog meters with no electronics (switch mode power supply) and also no transmitter is always preferred!  The switch mode power supply really affects people - has made countless people incredibly sick.  We have gotten countless phone calls over the years of people falling ill to electronic utility meters with switch mode power supplies - even without transmitters.  So a truly analog meter is all we can recommend for safety!!!

Removing it would be the best course of action - safest for sure. But measuring is always wise anyhow.  We can't assume anything about any gas/water/electric meters that are wireless.  Some transmit very frequently - as much as nearly ever second.  Some transmit one every few minutes.  Some are read on demand (fewer and fewer these days).  Most these days are transmitting at regular intervals many times per day.  So measuring is always the best way.

Luckily gas/water meters are much easier to shield and can be shielded much more effectively compared to electric smart meters.  So you also have that option as well - placing an effective barrier between the meter and your home.  This would block and reflect any transmissions that the meter puts out.

There are different designs for Cat7 cables - they are not all made equally.  That is why we carry cables that we recommend.  We never recommend flat fables.  Only round.  Most Cat7 with shield should be fine, but we always recommend our cables for high-quality cables you can count on: https://www.electrahealth.com/cat7.html

I don't think there is any law that could compel them to do something about it.  Only if the tenants made a stink about it - they might do something about it.  I would try having neighbors shutoff their breakers too to see if that lowers the fields.  What meter are you using to measure?
