ps. Old knowledge from old prior career experiences.
I use arc welding cables for connections, not 4 ga wire that takes a pipe
bender to work into place.
Welding cables, are multi wire, and that means "multi" with a capital.
Very flexible and capable of very high amps. It is for arc welding and
flexible use !

The way I understand this is that if we are in the USA, then our 240 volts is
likely Bi-Phase, not like Europe which has the Line swinging about the neutral
by 240 volts. In that case you can use a V LISN, or two single phase LISN’s.
In the USA with a Bi-Phase you need 3 LISN’s. When I test these, I use a 3
phase LISN rather than 3 individual LISN’s. It’s crazy to split the power cord
to reach the mains terminal on each LISN.
Take care listening to sales guys….
My 10 cents,
Derek.

I may be missing something here, but you would need a pair of LISNs for a box
that runs off a single phase and neutral. Most equipments of which I am aware
use the same power connector pins whether 120 or 240 V. In that case, you just
need one pair of LISNs. If for some reason your box runs off both 120 V and 240
simultaneously, then you would need two pairs of LISNs. Current rating is
whatever you need. I believe there are several manufacturers offering models
designed for up to 16 A. -- Ken JavorPh: (256) 650-5261 Hello and Happy
Friday, I've got a sales guy telling me our 120/240V EUT needs two pair of
single-phase LISNs for our CE test bench.That's only slightly cheaper than a
3-phase unit at > 50A, but very bulky. Can someone remind me why I'd need 4,
50A single-phase LISNs for our unit? I could see 3 (one for the neutral) but
I'm not so savvy on EMC test equipment. thanks, Colorado Brian From: Brian
