Best ElectricalOM Alternatives [2026]

ElectricalOM (formerly myCableEngineering) is a Nexans-backed cable sizing tool with strong BS 7671 and IEC 60364 implementations. It serves the UK and international market well within those two standards. But engineers look for alternatives when they need AS/NZS support, NEC compliance, offline capability, or broader calculation coverage.

This page examines the best alternatives to ElectricalOM, what each one offers beyond BS 7671 and IEC, and which fits your specific requirements.

Why Engineers Look for ElectricalOM Alternatives

The most common reasons engineers explore alternatives:

1. No AS/NZS 3008 support — Engineers working on Australian or New Zealand projects cannot use ElectricalOM. It does not implement AS/NZS cable sizing tables.
2. No NEC support — Projects governed by NEC/NFPA 70 (United States) are not covered.
3. Limited calculator types — ElectricalOM focuses on cable sizing. It does not offer arc flash, motor starting, conduit fill, earthing, or other calculation types that a multi-discipline platform provides.
4. No offline mode — No PWA or offline capability for site work without internet.
5. English only — No localised interface for non-English-speaking teams.
6. No team collaboration — No role-based access, project sharing, or multi-user workflows.

Alternative 1: ECalPro

Best for: Engineers who need AS/NZS, NEC, or multi-standard support alongside BS 7671 and IEC.

ECalPro covers all four major international cable sizing standards — including the two that ElectricalOM does not support (AS/NZS 3008 and NEC). With 27 calculators, offline PWA, and 23 languages, it is the broadest alternative.

ECalPro strengths over ElectricalOM: AS/NZS and NEC support, 27 calculators (vs ~10), offline PWA, 23 languages, team RBAC, arc flash, motor calculations, conduit fill, earthing, PPP pricing.

ElectricalOM strengths over ECalPro: Nexans manufacturer-specific cable data (verified against actual cable products), focused BS 7671 workflow refined for UK practice.

Choose ECalPro if you need more than BS 7671/IEC, work on international projects, need offline capability, or need team collaboration.

Alternative 2: ELEK Cable Pro

Best for: Engineers who need LV network design, protection coordination, or multi-method arc flash analysis.

ELEK supports BS 7671, IEC 60364, and AS/NZS 3008 (but not NEC). Its key differentiator is network-level design capability with real manufacturer device data.

ELEK strengths over ElectricalOM: AS/NZS support, LV network design, protection coordination, 20,000+ device database, 5 arc flash methods, SLD generation, AutoCAD export.

ElectricalOM strengths over ELEK: Simpler pricing model, Nexans manufacturer cable data for BS 7671, more focused interface for individual cable sizing.

Choose ELEK if you need network design, protection coordination, or AS/NZS support alongside BS 7671 and IEC.

Alternative 3: jCalc.net

Best for: Engineers who need to switch from BS 7671 to AS/NZS 3008 for Australian projects.

jCalc is an Australian-focused tool. It does not support BS 7671 or IEC — so it is only relevant if you are moving from UK/international work to Australian work, not if you want to add AS/NZS alongside your existing BS 7671 capability.

Choose jCalc only if you are moving exclusively to Australian standards. It is not an alternative for engineers who still need BS 7671 — it is a different tool for a different market.

Alternative 4: PowerCalc

Best for: Engineers who need NEC compliance tools with panel schedule features.

PowerCalc serves the US market with NEC-specific calculations. Like jCalc, it is not a like-for-like ElectricalOM replacement — it serves a different jurisdiction entirely.

Choose PowerCalc only if you are moving to US NEC work. Not relevant for engineers who need BS 7671 or IEC.

Alternative 5: ClearCalcs

Best for: Multi-discipline firms wanting structural + electrical + mechanical in one platform.

ClearCalcs is primarily a structural engineering tool that has expanded into electrical. Its electrical module is less specialised than ElectricalOM but offers the convenience of multi-discipline calculations in one subscription.

ClearCalcs strengths: Multi-discipline coverage, team features, modern interface.

ClearCalcs weaknesses: No BS 7671 or IEC 60364 — so it does not actually replace ElectricalOM's core capability. Only relevant if you are looking for a broader platform and do not need BS/IEC compliance.

Quick Decision Matrix

Comparison: Standards Coverage

This is the most critical differentiator. ElectricalOM covers BS 7671 and IEC 60364. Here is how alternatives expand that coverage:

Only ECalPro covers all six standards listed above. ELEK covers four. ElectricalOM covers two.

Frequently Asked Questions

Is ElectricalOM the same as myCableEngineering?

Yes. myCableEngineering was rebranded as ElectricalOM. It is the same tool, backed by Nexans, with the same BS 7671 and IEC 60364 coverage. If you are searching for "myCableEngineering alternative," the information on this page applies.

Does any alternative have Nexans cable data?

No. ElectricalOM's integration with Nexans manufacturer-specific cable data is unique. The alternatives listed above use generic standard tables (current ratings from the published standards themselves). For most engineering calculations, standard tables are sufficient — manufacturer data matters most for specialist applications where specific cable products have different thermal characteristics.

Can I use ECalPro for BS 7671 calculations if I am currently using ElectricalOM?

Yes. ECalPro implements BS 7671:2018+A2 cable sizing, voltage drop, and short circuit calculations. To verify, run the same inputs in both tools and compare results. The cable selections should match for standard installation methods and cable types.

Is ElectricalOM still a good tool?

Yes. ElectricalOM remains a strong choice for engineers who work primarily with BS 7671 and IEC 60364, particularly if Nexans cable data is valuable for your work. The reasons to look for alternatives are specific: needing AS/NZS or NEC support, needing offline capability, needing team features, or needing calculation types beyond cable sizing.

Which ElectricalOM alternative offers the best free tier?

ECalPro offers the most generous free tier for multi-standard work: all 27 calculators, 5 calculations per day, and watermarked PDF reports across AS/NZS, BS 7671, IEC 60364, and NEC. ELEK offers 6 free calculations per day for AS/NZS, BS 7671, and IEC 60364 (no NEC).
