Dear Group,
Consider a product that is intended
to be connected to mains power via a non- detachable power cord that is
fed into the equipment through a cable gland (compression bushing) fitted
to the equipment enclosure. Neither the power cord or the cable gland are
supplied by the manufacturer
Presumably, since you talk about an installer, this is a fixed product, not
a stationary or portable one?
If it's an installation, why is not just connected to fixed wiring ( by
whatever means the local safety regs require), rather than having a flexible
supply cord which emerges from the
Bit of a regulatory puzzler here, please bear with me.

Hi Grace,
That's a very useful document for measuring the RF path, thanks for the info.
The issue we have is that the RF path is not the only path for the emissions at
960MHz from the equipment under test so measuring just the conducted output
into the antenna would not give the whole picture.
Are you measuring according to DA 00-705? That should help.

Many high current products are shipped without power cords mainly because of
the wide variety of plugs and local electric code requirements for the cordage.
We ship our products with North American cords and plugs just out of our own
convenience but we know that in a very high number of
I think conducted measurements would not be helpful anyway, because in this
case the use of a conservative antenna gain value is required.

Hi Bob,
This is a Wi-Fi product which I believe is DSSS and not frequency hopping. I
will review the document anyway but will it be relevant do you think?
Many thanks

Not living in Europe I am most interested in this topic. Please educate me.
When you purchase an electric dryer or range in Europe, do they come with a
flexible power cord? Does it also come with a plug, if so what plug? For
instance, in North America for a 30 amp device there are 11 different

Yes - the limit line is essentially castellated between your -20dBc and the
applicable level in 15.209(a).
The 200dBuV/m limit doesn't apply to your equipment below the 960MHz transition
point - the -20dBc limit does.
