How do I know if my switchboard needs upgrading?

Ceramic fuses, no safety switches, flickering lights or breakers that trip when the kettle and heater run together are the classic signs. Upgrades range $770 to $3,225 because scope varies so much: adding safety switches to a sound board sits at the bottom, while replacing an asbestos panel and upgrading mains sits at the top. Tip: get the board assessed when buying an older home; it is a routine electrician visit at standard hourly rates, not a special service.
