Re: rack power 7+ how to tell if 3-phase power

In some cases not using a licensed electrician can also set you up for legal liability. Perhaps equipment is damaged. Worse perhaps a person is injured or killed.

At one of my customers their on site, and licensed, electrician wired the outlet for their then new 9406-720. It was our new sales person's first sale and she was excited to be on site for it to be powered on.

'SNAP!' and SRC 0000 0007. Game Over for the planar board. And it smelled bad.

Checking the outlet after the smoke came out, it was wrong. Fortunately because he was licensed IBM merely replaced the part. (Took hours of course and one had to be obtained.) Had he not been, IBM indicated they might have charged the customer.

Sadly the sales person suddenly wanted a drink, but the town was dry.

Quite.

While one does not have to be a professional electrician to know how to wire things to code, (and conversely, some professional electricians have been known to cut corners), *YOU DO HAVE TO KNOW WHAT YOU'RE DOING*

And if you aren't sure, with a certainty that comes from actual knowledge, rather than from what you *think* you know, then you're playing Russian roulette.
