Its not exactly appropriate to sell either lab on this list. Call ETL and they
can tell you.

Seems to me a commercial rather than technical issue... I can see the lawsuit
now: UL sues IEEE list server for deformation of character; IEEE sues posters

The requirement from CSA 22.2 No. 0.4 is now part and parcel
of the CSA/UL version of 60950-1. The 40 A current you
mention below is based a 20A branch circuit and applies to
mains PE. The current value used and the duration of the
test are dependent on the circuit size.
For instance,
Hi everybody,
I guess this is more of a safety thing, but I am sure that
somebody here can help me out. I am interested in finding out what kind

All,
I know that most of the general population is aware of the UL mark applied
to almost all appliances, equipment, etc, and that UL is the accepted safety

However, because of UL's reduction in staff ( which is causing huge
In college I had summer work in a metrology lab where I learned about
the real world.
I would caution anyone attempting 2 milliohm measurements to proceed
with caution.
Technology has made it easy for most anyone to make repeatable 50-100
milliohm measurements.
However, accurate measurements in
I disagree in principle with the other recommendations made for specific
meters. Nothing against the meters or the manufacturers, but there is no
simple answer. The answer depends on what you want your bond to do for you.
A 2.5 milliohm bond might be a class R bond, or class A or class L

Sir
Even with Kelvin leads, ground continuity measurements, even using a really
nice digital multimeter, may not be appropriate if you are testing for
compliance to an IEC60950-based standard. Also, milliohm-ranged measurements
tend to be susceptible to each individual's technique.
Note that
