Previous employer: Baker Hughes, Industrial & Energy Technology [1] [6]

A new leader for a long-established manufacturer

Ganesh Ramaswamy became Southwire’s president and chief executive officer in December 2025, succeeding Rich Stinson. The company confirmed him in the role in its 2026 announcements, including a July update to the executive team. The appointment brought an executive with experience across industrial technology and services into the leadership of the wire and cable manufacturer. [1] [2]

A career spanning products and services

Before Southwire, Ramaswamy had built a career across several kinds of industrial business. Johnson Controls’ 2019 appointment announcement described earlier leadership roles at General Electric, service as global president of Japan-based Pentax Medical, and assignments at Danaher. At Danaher, his responsibilities ultimately included four operating companies in product identification. [5]

Johnson Controls appointed him vice president and president of Global Services & Transformation in December 2019. The assignment included leadership of a global services business with revenue then reported at $6.3 billion. The company also identified his MBA from the University of Wisconsin and doctorate in mechanical engineering from the University of Pennsylvania. [5]

In January 2023, Baker Hughes named him executive vice president of Industrial & Energy Technology, effective January 16. His appointment was part of an organizational transformation intended to simplify operations and develop growth across industrial and energy markets. Southwire’s October 2025 announcement described that business as having $12 billion in revenue and more than 20,000 employees at the time. [6] [1]

Taking responsibility for the operating business

By February 2026, Ramaswamy reported that his early months at Southwire had included visits to facilities and meetings with employees and customers. That public update places his arrival in an operational context. The business he had joined remained family-owned, with roots in wire manufacturing and a history of expansion into higher-voltage products and research facilities. [3] [7]

The team shaping execution

Southwire’s July 2026 leadership announcement provides a more concrete view of the organization around him. It added executives in finance, people and culture, and digital information. Christy Wright’s responsibilities expanded to include supply chain and business systems, while Burt Fealing gained additional responsibility for operational sustainability, environmental health and safety, and community affairs. Ramaswamy identified the appointments as supporting execution of company strategy. [4]

For customers and suppliers, these assignments identify functions worth watching as the business develops. Procurement, operating systems and digital information influence how a manufacturer coordinates work; engineering support affects how its products are applied. Those responsibilities suggest that consistent execution across these functions will be a useful measure of Ramaswamy’s tenure as the company grows. [4] [8]

Why the Amp Rating on a Cable Is Only the Starting Point

Why the Amp Rating on a Cable Is Only the Starting Point

A current-capacity value is useful only when its assumptions belong to the installation being designed. The route and the termination deserve equal attention.

By Grant MercerPower distribution & reliability

3-minute read

Two cable quotations can show the same conductor size and still leave the most important design question unanswered: under what installation conditions is the cable expected to carry the load?

That question is not an argument for routinely buying larger cable. It is an argument for connecting the cable schedule to the actual installation. A larger conductor selected without reviewing the route, terminations, and equipment requirements can move the problem instead of resolving it.

A rating belongs to a set of assumptions

LAPP’s current-rating guidance identifies installation method, ambient conditions, conductor temperature, and grouping among the considerations used when determining current capacity. Its reference information includes correction factors because an installation can differ from the reference case. ^[1]

For a project owner, the first useful question is therefore about the source of the value. Which table, calculation, or manufacturer recommendation is being used? What cable construction and operating conditions does it cover? Which edition and jurisdiction apply to the actual installation?

Those are questions for the responsible electrical designer. Purchasing should obtain the approved result and its assumptions, rather than selecting the most favorable number found in competing literature.

Review the route as a whole

Treat the route drawing as an input to sizing, not merely an installation convenience. Ask the design team to identify sections with different conditions: a tray, an enclosure entry, a grouped run, or a location with a different expected ambient temperature.

This does not mean every change produces the same correction. It means the reviewer needs to know the changes exist. A cable schedule that records only origin, destination, and total length may omit the conditions the designer needs to evaluate.

A practical project rule is to return meaningful route changes to engineering before installation proceeds. Additional circuits, enclosure changes, or a rerouted section should not be treated as purely logistical decisions until their design implications have been checked.

The termination is another boundary

UL’s Wire and Cable Application Guide emphasizes selecting products for their intended use and interpreting the relevant markings and certifications. That review belongs alongside the equipment documentation, not in place of it. ^[2]

Ask the equipment supplier to confirm the permitted conductor construction, size range, temperature limitations, and termination method for the actual connection. Do not infer the complete equipment rating from the insulation temperature printed on a cable jacket.

Consider a proposed increase in conductor size. Before approving it, ask whether the new conductor is accepted by the specified terminal and whether the approved entry and routing arrangement can accommodate it. The cable change needs a complete interface review; it should not require the installer to improvise a fit.

Keep separate calculations separate

Maintain a short design record with distinct conclusions. Record the approved current-carrying selection, the voltage-drop review, the equipment and termination compatibility check, and the applicable protection requirements as separate items.

That makes the decision easier to audit. A satisfactory answer to one question should not be allowed to masquerade as an answer to all four. The record can be brief, but it should show who approved each conclusion and which installation assumptions were used.

Avoid copying a generic sizing example into the project as though it were a finished calculation. Worked examples explain a method; they do not establish the operating conditions, governing requirements, or equipment details of a different installation.

Give procurement a controlled selection

Release an exact cable specification or a clearly defined approved-equivalent process. Include the construction, required markings, quantity basis, and installation assumptions that must remain unchanged. State which substitutions require engineering approval.

If a supplier offers an alternative, have the reviewer evaluate the differences explicitly. The useful comparison is not simply “same gauge, lower price.” It is whether the alternative satisfies the released requirements without creating a new constraint elsewhere.

A cable’s current rating is a necessary piece of information. It is not the entire design. The stronger purchasing decision is the one that carries the design assumptions all the way from engineering to the delivered cable—and brings proposed changes back through the same review.

The practical takeaway

Carry the approved installation assumptions all the way from engineering to the purchased cable.

The Connector Is Part of the Power Circuit—Not an Accessory

The Connector Is Part of the Power Circuit—Not an Accessory

A power connection deserves the same engineering attention as the cable feeding it. Start with the circuit, then evaluate the complete interface.

By Grant MercerPower distribution & reliability

4-minute read

A connector should not become the leftover decision after the cable, drive, and enclosure have been selected. It is an intentional break in the circuit, assembled from parts that must work together. The practical question is not whether a connector looks substantial enough. It is whether the specified interface is suitable for the load and conditions it will actually encounter.

That calls for a different purchasing conversation. Instead of asking only for an amperage and a price, ask the supplier to identify the complete configuration behind its recommendation. A connector family name is a starting point, not a finished specification.

Read the conditions behind the rating

Phoenix Contact’s electrical-test guidance explains that current capacity must be considered in relation to ambient temperature and the loading of neighboring contacts. Its test descriptions also identify the conductor configuration used during evaluation. Those details matter when comparing a catalog number with a crowded, operating enclosure. ^[1]

The purchasing implication is straightforward: request the applicable current-temperature information for the intended contact arrangement and wire size. Have the responsible designer compare it with the installation. Do not invent a universal percentage reduction or assume a larger shell eliminates the need for review.

Ask a second question at the same time: what changed between the evaluated assembly and ours? A different contact population, termination method, conductor, or enclosure arrangement should trigger an engineering check rather than an optimistic interpretation of the headline rating.

Specify the interface, not a shopping list

Build the connection specification around a mating pair. Identify both halves, the contact system, the approved conductor range, the termination tooling, and the cable-entry components. Include the manufacturer’s assembly instructions in the released package.

The purpose is to reduce ambiguity, not to prescribe the same construction for every connection. A crimped, bolted, screw-clamped, or spring-connected interface will have its own instructions. The team should be able to show which instructions apply without searching an old email during installation.

Environmental and mechanical tests are separate parts of connector evaluation. Phoenix Contact’s laboratory overview lists distinct test categories rather than treating one electrical rating as proof of every performance characteristic. ^[2] Use that distinction when a substitution is proposed: matching electrical numbers does not, by itself, answer the mechanical or environmental questions.

Put the installer’s questions in the drawing

Picture the installation review before releasing the order. Can the approved cable enter the housing without an improvised modification? Is there room to use the specified tooling? Can the installer identify the correct cavity and conductor without interpreting an ambiguous view? Can the assembly be inspected before it disappears behind another component?

Record the answers as dimensions, part numbers, views, and instructions—not as assumptions about the installer’s experience. Where an assembly method calls for a specified torque, reference the manufacturer’s requirement and the applicable joint. Do not turn a number from a different connector into a plant-wide rule.

Electrical installation or intrusive inspection belongs under the site’s approved procedures and qualified personnel. Deenergization and the applicable energy-control process are not optional conveniences to be traded against a production schedule. ^[3]

Decide how the connection will be replaced

A useful selection review includes a replacement rehearsal on paper. Name the item that maintenance will order. Identify what arrives assembled, what must be transferred, what tools are required, and what verification is needed before return to service.

Consider two quotations that initially appear equivalent. One includes a defined mating pair and assembly documentation. The other lists only a generic connector description. The first does not automatically represent the better product, but it provides a more complete basis for comparison. Ask the second supplier to close the information gap before comparing price.

The release decision

Before approval, require one person to own the connection as a complete interface. That owner should resolve rating conditions, installation requirements, environmental suitability, and replacement identification with the relevant specialists.

The goal is not to make a simple connector purchase bureaucratic. It is to stop a critical circuit boundary from falling between responsibilities. Select the cable and connector together, document the installation, and leave the next team a configuration it can recognize and reproduce.

The practical takeaway

Select the complete power interface—not just a connector with a familiar amp rating.
