Shame on me, I ordered the CT’s with my emonPI I knew my wire was not AWG 4/0 but did not double check that it was AWG 2/0. my emonPi arrived today, I went to install but of course the CT’s do not fit as the wire is ~15mm in diameter. Looking through the threads and info here I am not sure what CT’s I should get.
Have a look at the “Use in N.America” page. There are several makes listed that we know are OK with the emonTx/emonPi, check the dimensions against your cable overall diameter, and be prepared to change or remove a couple of resistors inside your emonPi (unless you choose the SCT023R) and solder plugs onto the c.t. leads.
ordered a pair of these. will have to wait a few weeks for them to arrive
