Your electrical switchboard is the heart of the home and unfortunately many home owners fail to keep it up to current standards.
An outdated switchboard can be the cause of nuisance tripping/overload, house fires and electrocution, an old switchboard may also contain asbestos which can be dangerous to everyone in the household especially if the switchboard pre dates the 90s.
Once an electrician upgrades your switchboard, you can rest easy knowing that your home is protected completely by safety switches (RCBOS) which not only protect you from electrocution but also protect the cabling in your home from overload.
