I had power going to a switch and a plug out let but I had to change them out once I did they are both on two differnet breakers . Once they where changed I turned the power back on and the breakers instantly blew so I replaced them with new ones and turned the power back on and got nothing out of the switch or outlet so I checked with a multimeter at both and got no reading so I checked it at the breakers in the box and got no reading there so now half of my house is out of power when it was all working what could be causeing the problem and how can I fix it so I have power again please help fast I have children and need the power
