If you don't see continuity, it's an unknown, in which case I'd replace it with a GFI breaker (since you want to do that anyway) and see what happens. <div><br></div><div>jim<br><div><br><blockquote type="cite"><div>On Feb 1, 2025, at 11:03 AM, Tim . <tims_datsun_stuff@outlook.com> wrote:</div><br class="Apple-interchange-newline"><div><meta charset="UTF-8"><div class="elementToProof" style="font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt;">The breaker that controls my sink grinder's outlet seems to have failed.

Near as I can tell that breaker only has one outlet on it. (house was built in 1905 or so and still has active knob and tube. ffs. And there are at least four breakers controlling our tiny kitchen.) Also, the outlet is not GFI so I want to replace it but can't really fit under the sink to do it. </div><div class="elementToProof" style="font-style: normal; font-variant-caps: normal; font-weight: 400;
