Twitter’s top ranks were riddled with ex-FBI agents and executives, stitching the company even closer to the federal agency now under fire for leaning on Twitter to meddle in the 2020 elections.

More than a dozen former feds flocked to the company in the months and years prior to Elon Musk’s purchase of the social network in October.

The Post found FBI influence was considerably more significant than just James Baker, the FBI’s former general counsel who later worked in the same role for Twitter. He was recently fired by Musk for interfering in the billionaire’s efforts to come clean about past transgressions at the company.

In some cases, the former G-men and -women held positions that would have put them close to company leadership directly involved in censoring The Post’s Hunter Biden coverage in October 2020.

• What is the key point to make the decision of paralleling?
  ** Reliability and redundancy.

• Do you use 4 pole or 3 pole ATSs on 120/208V Y systems

** To determine which configuration (3-pole or 4-pole) to select, attention must be paid to the system grounding scheme and ground fault protection requirements. If ground fault detection is required on either source, a 4-pole transfer switch is necessary in most cases. Per NFPA 70: National Electrical Code 230.95 Ground Fault Protection (GFP) of equipment is required at the service disconnect (utility breaker) for systems with all of the following:

Solidly grounded wye electrical service.
More than 150 volts to ground (277/480 or 347/600 VAC).
Over current device rating of 1000 A or more.
NEC 700.6 (D) and 701.6 (D) requires Ground Fault Indication (GFI) at the emergency source.

Ground fault sensing depends on being able to sense ground fault current. To accurately sense ground fault current, it must return to its source on a known path relative to ground fault current transformers (CTs). In basic emergency standby systems there are two rules to follow to meet these requirements:

There can only be one neutral/ground connection on any neutral bus at one time.
Ground fault sensors (the CTs) must be downstream (or on the load side) of the bonding connection.

To meet both rules when connected to either the normal or the emergency source, the neutral must be switched using a 4-pole transfer switch

According to Clayton Christensen, a professor at Harvard Business School, it wasn’t a lack of trying that took down DEC. It was the inflexibility of the business model they had so long relied upon:

“Digital Equipment Corp. had microprocessor technology, but its business model could not profitably sell a computer for less than $50,000. The technology trapped in a high-cost business model had no impact on the world, and in fact, the world ultimately killed Digital. But IBM Corp., with the very same processors at its disposal, set up a different business model in Florida that could make money at a $2,000 price point and 20% gross margins—and changed the world.”
