18EATON CORPORATION BR003010ENQuestions about retrofittingQuestions about added value and cost factorI already have an electrical installation, but I would still like to protect my home. Can I retrofit it with an AFDD?No problem; an AFDD can be built into an installation at any time. Usually, there are additional slots available for an extension. When retrofitting a home installation with an AFDD, the introduction of a combination device with a residual current and an MCB function is worth considering.However, the retrofitting needs to be performed by an electrically skilled person.What added value emerges from the use of an AFDD?The additional protection against electrically caused fires provides comprehensive protection for electrical systems and their supplied premises. This simple measure can actively prevent damage to human beings and goods.Is it really necessary to install an AFDD?With older electrical installations, it was not yet possible to install an arc fault detection device, so these systems had no way of detecting active arc faults. Therefore, electrically caused fires used to occur, injuring and killing many people and causing countless millions, even billions of euros worth of damage to building structures, machines, installations and goods. Oftentimes retrofitting or installation is not legally mandatory, but it is possible, and it is the only way of protecting homes, property and goods actively. The decision of whether or not to install this protective device, if there is no legal requirement to do so, lies with each individual.What additional costs must be planned for projects?As additional costs do not affect every circuit, but only the final circuits for which the AFDDs will be installed, the added value gained is clearly higher than the additional costs incurred.
