After turning off the braker and lock out🔐 installation, they never check the power in the old transformer and put their hands over those bars, assuming everything is fine...
Hi Gustavo, This video is intended merely for informational purposes ONLY, not instructional. You should always have this kind of work done by licensed and experienced electrical contractor who is familiar with installing transformers.
you know why transformers hum? because they don't know the words. these xfmrs need annual maintenance, aka a shutdown, to vacuum dust build up and torque the lug connections.
Absolutely, regular maintenance is the best way to increase your transformer’s life. For liquid-filled units, we created this resource around Dissolved Gas Analysis (DGA) Tests and oil samples: www.maddoxtransformer.com/resources/articles/transformer-maintenance-dissolved-gas-analysis-and-how-to-pull-an-oil-sample/
I liked the lockout, tagout but expected to see a check for potential prior to making any kind of disconnection. Also expected to be shown the checking for phase rotation using a Knopps or similar device plus measured voltage output values, etc.

Hi Jermaine, We always recommend using a licensed electrical professional when installing these units, who can perform electrical testing on the transformer. For more information about transformer testing please check out this guide: www.maddoxtransformer.com/resources/articles/guide-to-transformer-testing-standards/
Awesome work

Why is there two metal flexes going in on the high side
Parallel feeds on the secondary side

I noticed the transformer was not commissioned via any electrical testing.

When in doubt megger it out.
260.64(g) Grounding electrode conductors shall not be installed through a ventilation opening of an enclosure. NEC 2023
Wear a suit when you energize that unit
is the transformer connected directly to the incoming power with a shutoff then to a panel?
Transformers like these are fed from the switchgears/switchboards which are fed from Edison/incoming power to vicinity
That hole looks like crap and with the vibrations can nick the wire coming in from the bottom. FAIL.
Good thing those guys are wearing masks. Safety first. 🙄
Now anyone can do it!
Don’t really try this at home. You might hook it up incorrectly and then go boom boom
Absolutely, make sure you use an experienced electrical professional to install your transformer.
Loud buzzing noise (just a loose cover) , REPLACE IT !!!!
Don't need Noalox, but ok.
Could be job spec or manufacturer’s instructions.
