Dear Members
I'd like to solve a doubt.. suppose the following:
I have an electrical installation in a house. The feeding is with
three-phase and one neutral conductors. If I connect a TV and a blender
in the same phase, the blender generates interference (lines) in the TV
screen. If I connect
Trying to be helpful, and I create more trouble...oh well...
some people were not able to open the Word document I attached to a previous

Here is the same document saved as RTF. Hope this helps.

Yes we hit this problem several years ago, hence my qualifier of

I had the opposite problem once, of ensuring electrical connection to an
anodised aluminium part, for shielding purposes. The only sure way was to
machine away the anodising on the surface where contact was to be made.
But that is quite different from relying on the anodising for insulation,
Could anyone please provide me with the name and contact information for
any EMC testing facility

Paul,
I believe the requirement is related to flammable liquids such as gasoline
and LP gas. For example in gas stations electrical components are
typically installed at least 18 above the ground. Additionally, my hot
water heater at home is on an 18 stand. The NEC covers some of the

Given that sulphuric hard III anodizing is only .001 to .003 thick then I'd
have thought not. It is also fairly easy to compromise, so in a mechanical
assembly you would be hard pressed to know how good the insulator was or how
long it would remain so after the rigours of use (vibration etc.).
Don , Please allow me to input a wild speculation.

A question regarding the Universal Serial Bus (USB) Specification.
USB spec. 1.0 required the cable shield at the peripheral end to be DC
isolated from the chassis; ie, it could be terminated only through a

max. length of 5
