Re: [PSES] TRAVEL ADAPTORS-EU regulation that forbids use in professional equipment?

[MIKE SHERMAN]

It looks very promising.
My only hesitation is that the two screws that hold this together do not appear 
to be tamperproof, which is a requirement for these types of adaptors in 
Australia, but may not be a requirement in the UK. I would think you should be 
able to find a helpful regulator in the UK who could address this, or maybe 
even the people at PowerConnections.

[PSES] What are the dates for 2021 PSES & SPCE conferences?

[David Huff]

COVID cancelled the Chicago PSES 2020 conference, and forced the SPCE to go 
virtual.  I am wondering if anybody knows the dates & locations for 2021 IEEE 
PSES and SPCE related conferences?

My company now requires me to book these things as far out in the future as 
possible, because last minute hotel & plane tickets are getting really 
expensive.

As a note, the IEEE SPCE 2020 PDF of events it is so blurry, it was very hard 
to determine if my boss would let me spend $185 to do virtual events like this.


Thanks,
David Huff

[PSES] URGENT: Need an FCC compliance consultant and some labs in Texas

[Doug Nix]

Colleagues,

I received a call from a client of mine that is in the construction equipment 
sector. They build programmable traffic control signage and arrow boards among 
other products.

They have an urgent need for help with FCC and Industry Canada declarations, 
and they have no internal expertise at the moment. Additionally, they need a 
lab in the Houston area where their manufacturing plant is located.

If you are qualified and interested, let me know. I will happily pass your 
information on to my client and let them contact you. This will be a straight 
referral from me, with no other involvement by me.

Re: [PSES] Use of Electrical Enclosure as the Ground Bus

[Stultz, Mark]

Hi Curt,

Originally the enclosure was going to be conversion-coated Aluminum and the 
ground lugs were Tin-plated.  In the unending quest for cost reduction, this 
changed to a galvanized steel enclosure with plain brass lugs.  The zinc/brass 
match set off all sorts of galvanic corrosion alarm bells for me which is what 
prompted re-reading the standards.  This machine will be sold worldwide, but 
mostly in the US, Canada, and the EU.  We typically apply IEC 60204-1 for 
electrical safety and EN 415-10 (Packaging Machinery: General).

Thanks,

 CAUTION: This email originated from outside of the organization. Do not click

is safe.

In my experience enclosure metal is usually not satisfactory for a low 
impedance connection that remains corrosion free.

Aluminum is typically anodyzed, and anodyzing is (mostly) non-conductive.

Most steel is painted or plated. Clearing off the surface coating will allow 
corrosion to happen.

There are some plating processes which could allow a low impedance connection. 
It is critical to examine the materials that come in contact with each other, 
as many combinations will lead to corrosion after installation.
https://www.sharrettsplating.com/base-materials/aluminum

My understanding is that if the metal types are the same, the risk of corrosion 
is lower. Check out the chart on the lower right of this page.
https://galvanizeit.org/corrosion/corrosion-process/galvanic-corrosion

It is possible to get ground studs installed at time of enclosure manufacture, 
it will reduce these risks.

What market is this for, and what safety standard will be applied?

Curt McNamara, P.E.

Hello,

copper busbar and reduce the length of bonding wires inside the enclosure.

IEC 60204-1 appears to allow this with stipulations:

Metal enclosures or frames or mounting plates of electrical equipment,

conductors if they satisfy the following three requirements:

connection so as to ensure protection against mechanical, chemical or 
electrochemical deterioration;

* they comply with the requirements of 543.1 of IEC 60364-5-54:2011;

* they shall permit the connection of other protective conductors at every 
predetermined tap-off point.
NFPA 79 appears to not allow this (unless the enclosure were made of copper...):

8.2.2.1 Conductors used for grounding and bonding purposes shall be copper. 
Stipulations on stranding and flexing as outlined in Chapter 12 shall apply.
What are your thoughts on connecting the bonding system this way?  Is NFPA 79 
as inflexible in this regard as I am reading it?
