Noise on the breaker of my bath line
Hi,
Today, while working on the electrical panel, I noticed a buzz coming from the bath breaker.
My wife uses a 3000W Step UP / DOWN Voltage Transformer for her iron, we have been using these converters since we moved to Canada from Europe without any problem.
The noise can be heard whenever the converter is switched on, it lasts approx. 20 secs, then disappears, however when the iron demands power, for instance, to keep its temperature, the buzz can be heard at the breaker panel for another 20 secs.
Is this normal?

Turn off the main breaker and see if the buzzing breaker is loose. pull the breaker and see if there is any damage to the buss bar.
That is grater than the capacity of a North American 120 volt receptacle. What is the actual watts of the iron?

It is not that unusual for a large load to buzz slightly when first starting up, especially if the load is near or over the rated capacity of the circuit. It can be the magnetic trip mechanism in the breaker vibrating a small amount from the surge. Continued or excessive buzzing is a sign of a problem. Buzzing in conjunction with smoke or burning smell is also sign of a problem.
