Start with the residual-current characteristics of the circuit<\/h2>\n<p>The first question is not which label sounds more comprehensive. It is what residual-current characteristics the circuit documentation expects the device to address. The load list, circuit schedule, supply arrangement, and the selected-device record turn that question into a reviewable technical request.<\/p>\n<p>For a panel buyer, that means keeping the electrical scope visible before price comparison begins. A request that only says &#8220;Type A&#8221; or &#8220;Type AC&#8221; leaves the supplier to infer the load, sensitivity, and circuit boundary. The drawing and load description should instead establish why that type is being considered.<\/p>\n<h2 id=\"part-2-what-type-ac-and-type-a-labels-do-in-a-review\">Part 2. What Type AC and Type A labels do in a review<\/h2>\n<p>Type AC and Type A identify different residual-current detection characteristics. Type A is associated with circuits where pulsating DC residual current needs to be considered; the selected model, circuit evidence, and applicable project requirements still determine what belongs in the final design.<\/p>\n<p>The label is therefore one field in a wider evidence set, not a shorthand for installation approval. Manufacturer documentation and the IEC standards system are useful places to locate the selected-device record, while the approved design remains the reference for the circuit itself.<\/p>\n<blockquote><p><strong>Importante:<\/strong> A Type AC\/Type A label should never override the documented circuit requirement. Review the load record and the exact product documentation before the type is finalised.

Compare the evidence before selecting a type<\/h2>\n<p>Putting both routes beside the same review questions prevents a broad product family description from becoming a project assumption. The table is a comparison aid, not a wiring diagram or a final type-selection rule.<\/p>\n<table>\n<thead>\n<tr>\n<th>Rever entrada<\/th>\n<th>Type AC review route<\/th>\n<th>Type A review route<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Circuit and load description<\/td>\n<td>Identify the stated residual-current characteristics in the drawing and load record<\/td>\n<td>Identify the stated residual-current characteristics in the drawing and load record<\/td>\n<\/tr>\n<tr>\n<td>Device type request<\/td>\n<td>Record the requested Type AC marking and selected-model evidence<\/td>\n<td>Record the requested Type A marking and selected-model evidence<\/td>\n<\/tr>\n<tr>\n<td>Sensitivity<\/td>\n<td>State the required residual-current sensitivity for review<\/td>\n<td>State the required residual-current sensitivity for review<\/td>\n<\/tr>\n<tr>\n<td>Supply and poles<\/td>\n<td>Match the supply arrangement and pole requirement to the model record<\/td>\n<td>Match the supply arrangement and pole requirement to the model record<\/td>\n<\/tr>\n<tr>\n<td>Supplier documents<\/td>\n<td>Ask for the exact product identification and documentation<\/td>\n<td>Ask for the exact product identification and documentation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<figure style=\"margin: 26px 0; text-align: center;\"><\/figure>\n<p>An evidence-led comparison also keeps product fields in their proper place.

Connect the load record to the supplier request<\/h2>\n<p>Give the supplier the circuit record that made the type comparison necessary.
