It's B.
The truth is that the breaker isn't broken, it's the only thing in that wall doing its job.
→ Your microwave pulls around 1,200 watts. Your toaster pulls about the same.
Run them together and you're asking for roughly 2,400.
→ A standard 15-amp kitchen circuit tops out at 1,800.
And it shouldn't sit above about 1,440 for any length of time. You're over before the toast pops.
→ So the breaker opens.
That's not a malfunction. That's a device noticing the wire behind your wall is being asked to carry more than it can, and shutting it down before it gets hot.
→ A breaker that doesn't trip is the dangerous one.
That's a whole other post, and it's the reason we flag certain panel brands the second we see the label.
Why not the others: a loose neutral usually shows up as flickering, or lights that brighten when something kicks on, not a clean, predictable trip. And if the microwave itself were faulty, it would trip on its own, not only when the toaster joins in.
The fix is another circuit, not a bigger breaker.
Modern kitchens get dedicated circuits for countertop appliances. Cincinnati's median home was built in 1951, and a lot of those kitchens are still running everything off one circuit that was sized for a percolator.
Here's the part that costs us money to say: if this happens once a month when you're doing something unusual, you probably don't need us. Plenty of people live with it for years and nothing ever comes of it.
If it happens every week, that circuit is running hot on a regular basis, and that's worth an hour of somebody's time.
What we'd ask is that you don't let anyone "solve" it by putting a bigger breaker on the same wire. The wire doesn't get bigger. That's the most common thing we find that turns a nuisance into a fire.
