Hi Guillermo
Unless they are single punctual charges, it does not make sense to limit the way you propose a line of shots when it is a family home. A 2.5 mm circuit can quietly withstand a continuous amperage of around 20 amps without even taking temperature, so I do not consider it advisable to advise installers or users in general to put thermomagnetic protection of 10 A.
You can always put smaller protections to extend the security band, but in the case that is justified, or we would like to do on a personal level. Never as a rule. Health
nastor, good afternoon, how strange that you do not see sense, and that's why I clarified, here in Uruguay the limiting key that is installed in power supplies 3.7kw is 16A. therefore the thermals that are connected downstream for derivations should be of a lower amperage, so that just before a high consumption in the line does not trigger the general and only trigger the thermal of that derivation. If the general termica has a value higher than 16 amper, no problem can be placed 16a thermals for shunts of current, greetings.
