No power to garbage disposal and dishwasher after new install

Replacing a garbage disposal often trips the breaker or unseats a wire in the outlet box they share, cutting power to both appliances at once. Because the circuit is overloaded or a connection came loose during installation, neither unit will turn on until the breaker is fully reset or the wiring connections are checked.
