I recently added an outlet in my kitchen for a under cabinet microwave off of an existing circuit. Before mounting the new cabinets and covering up everything, I was unsure if the new setup could handle the load of the new microwave. I borrowed a friends' clamping ammeter and saw that with microwave running and exhaust fan blowing on high, it uses 16.8 amps. The outlet and wire (romex) I bought was only for
15amp circuit. The breaker didn't switch, I'm assuming it's on a 20amp circuit. It measured only 14.5amp with microwave running only. Although, I'm not exactly sure about what else is running off the circuit.Is the fix to just update the wire and outlet to handle 20amps? Or do I need a dedicated line for this. All other outlets on circuit are GFCI outlets, 15amp max (I believe).
If it requires > 15amp circuit, then why doesn't the plug have the one T shaped pin?
Please advise.....I will call electrician to inspect after it's complete. But I want to understand it first.
