EMC vs Low Voltage Directive comparison for electrical equipment
Use the EMC Directive for electromagnetic emissions and immunity. Use the for electrical safety when equipment is designed for 50-1,000 V AC or 75-1,500 V DC and no LVD exclusion applies.
Many mains-powered products need both routes. Assess each law separately, then identify both in the EU declaration of conformity when both apply.
Many electrical products need both analyses. Directive 2014/30/EU addresses electromagnetic disturbance and immunity. Directive 2014/35/EU addresses the safety of electrical equipment designed for use between 50 and 1,000 V AC or between 75 and 1,500 V DC, except the equipment and phenomena listed in its Annex II. Falling outside those voltage limits does not remove EMC duties and does not prove that no other EU safety law applies.

Practical decision rule
How to decide whether EMC, LVD, or both belong in the release pack
Start with the product boundary: finished apparatus, combination of apparatus, component for end-user incorporation, mobile installation, or fixed installation.
Ask the EMC question first: emissions, immunity, electromagnetic environment, installation precautions, and EMC harmonised standards.
Ask the LVD question separately: is the equipment designed for 50-1,000 V AC or 75-1,500 V DC, does an Annex II exclusion apply, and does product-specific law change the safety route?
Use one CE evidence index only if it clearly tags which documents support EMC, LVD, or both.
Escalate before release when the DoC names a directive that has no supporting assessment, standard, test report, or technical documentation.
Supports checking all applicable Union harmonisation legislation and applying complementary product laws simultaneously where appropriate.

Section 1
What the EMC Directive covers that LVD does not
Directive 2014/30/EU regulates electromagnetic compatibility of equipment. Its subject is not electric shock, fire, thermal, mechanical, or other safety hazards; it is whether apparatus or fixed installations can function in their electromagnetic environment without introducing intolerable disturbance to other equipment.
Directive 2014/35/EU covers electrical equipment within its voltage limits and requires it to meet the safety objectives in Annex I when properly installed, maintained, and used for its intended purpose. Annex II excludes specified equipment and phenomena, including electrical equipment for use in an explosive atmosphere, radiology and medical equipment, parts for goods and passenger lifts, electricity meters, electric-fence controllers, radio-electrical interference, specialised equipment for ships, aircraft, or railways that complies with international safety provisions, and certain custom-built evaluation kits.
Use the EMC column when the risk is electromagnetic disturbance, degraded performance from disturbance, immunity, a fixed-installation interface, or a harmonised EMC standard.
Use the LVD column when the equipment is within 50-1,000 V AC or 75-1,500 V DC, no Annex II exclusion applies, and the issue is electrical safety rather than compatibility with the electromagnetic environment.
Use both columns where the same electrical product must show complementary EMC and electrical-safety compliance before CE marking.
For example, a mains-powered household appliance can require both EMC disturbance and immunity evidence and LVD electrical-safety evidence. A device designed only for 24 V DC falls outside the LVD voltage range, but that fact does not remove an EMC assessment or any safety duties imposed by another applicable Union act.
Explains that multiple EU product laws may apply to one product when they cover complementary hazards or impacts.
several pieces of legislation may have to be taken into consideration for one product

Section 2
How overlap should be handled in the CE file
Do not merge EMC and LVD just because one product bears one CE marking. The manufacturer still needs evidence that each applicable Union act has been assessed and that the relevant conformity assessment procedures have been completed.
Both directives require the manufacturer to prepare technical documentation, complete the applicable conformity assessment, draw up an EU declaration of conformity, affix CE marking, provide identification and contact details, and retain the technical documentation and declaration for 10 years after the product is placed on the market. LVD uses internal production control; EMC also permits EU-type examination followed by conformity to type based on internal production control. The technical evidence differs: EMC evidence addresses disturbance and immunity, while LVD evidence addresses the Annex I safety objectives.
Keep one evidence index, but tag each report, standard, assessment, instruction, and declaration line to EMC, LVD, or both.
Where the apparatus is subject to more than one Union act requiring an EU declaration of conformity, use a single EU declaration that identifies all Union acts concerned and their publication references.
Reopen the comparison when product design, intended use, installation context, supplied components, importer/distributor role, or harmonised standards change.
Articles 6, 14 to 18, and Annex III establish manufacturer duties, internal production control, technical documentation, the EU declaration of conformity, CE marking, and 10-year retention.
Supports treating CE marking as the manufacturer's declaration that applicable Union harmonisation requirements and conformity assessment procedures have been fulfilled.

Recommended next step
Check the EMC and LVD evidence before release
This comparison helps separate electromagnetic compatibility claims from electrical-safety claims, then align the standards matrix, technical documentation, EU declaration of conformity, and CE marking evidence.
Harmonised standards can simplify evidence, but the standard must match the requirement it supports. EMC harmonised standards cited in the Official Journal support the EMC essential requirements they cover; they do not automatically prove LVD safety objectives. LVD standards cited for Directive 2014/35/EU support only the safety objectives they cover.
The practical control is a standards matrix. List every applied standard, its OJEU reference or source, the product configuration tested, the requirement covered, the test report or assessment evidence, and whether any superseded or withdrawn reference affects the release.
Use EMC standards for emissions, immunity, electromagnetic environment, and related compatibility claims.
Use LVD safety standards or another documented technical solution for electrical-safety claims; do not cite an EMC immunity report as proof of electrical safety.
Where one test lab package supports both regimes, split the evidence lines so each claim still points to the correct directive and standard.
Articles 12 and 13 establish presumptions of conformity through cited harmonised standards and, in specified circumstances, international or national standards.
