Review on ⚡️ High-Performance Siemens Q2020 120V Breakers by Andrew Lyons

My existing breaker for an old ITE panel is failing. Tripped for no reason. I checked the wiring, it's ok by me hooked up another switch. Most hardware stores, including Home Depot, don't have them. I'm checking my 1" C/B called Model QP. This breaker is QT (called QT because it is 1/2 size with 2 slots). I read an earlier comment from another reviewer that it doesn't fit. Another person refuted and said that it is suitable for the ITE panel. I took the risk of buying 2 20A QT and 1 15A QT. I bought an extra one because of the free shipping and kept it for parts as it's hard to find a C/B for an ITE panel. Fits perfectly and tightly. I have to wiggle it a bit to make it fit. This confirms that it is SUITABLE
