No power at outlets and lights, no bad breakers
Are all the outlets / lights on 1 circuit, If so find the last working device from the panel or the First non working device, I find back stabs are the cause for this type of problem in the high 90%. In this case the failed junction may be at a light switch where the outlet is also powered via a splice before the switch, the other possibility would be where a outlet feeds the switches. As I said at the start most times I find this problem it is from a failed back stabs in a 15 amp circuit. I have found both 15 &amp; 20 amp circuits that have had a loose wire nut or a broken wire usually right at the point where the wire was stripped. These are the main failures I have found over many years with daisy chained circuits.
