I accidentally ordered the 200-amp clamps for my 100-amp service panel. Is my accuracy going to suffer significantly to the point where it’s worth ordering the 100-amp clamps, or should I just install the 200-amp clamps? I had read somewhere you should use the smallest clamps that meet your amperage. Just looking for opinions. Thanks.
The 200 Amp CTs will work fine. The most significant impact was on your pocketbook.
