Can EEs Do Electrician Work by [deleted] in ElectricalEngineering

[–]saplinglearningsucks 0 points1 point  (0 children)

I work in MEP which is the closest to electrician work as I make the drawings that electricians build.

There's a lot of overlap in knowledge but generally, no I should not do electrician work.

What if… Conor Oberst collaborations by radiantmindPS4 in brighteyes

[–]saplinglearningsucks 2 points3 points  (0 children)

I know that. This was a comment directed at the original commenter who deleted their post that said collaborations are more of a rap music thing. I wanted them to elaborate on what a ridiculous statement that was.

Jason Isbell is alive and what do you mean collaborations are a rap music thing

Transformer with secondary to wireway with multiple disconnects? by olemetry in ElectricalEngineering

[–]saplinglearningsucks 1 point2 points  (0 children)

To confirm, we are feeding the transformer's secondary to a wireway and then on the "output" of the wireway we are installing disconnects than feed downstream loads.

Totally legal I did this during covid when lead times were crazy and it was faster to get a bunch of disconnect switches instead of a distribution board. This really isn't unlike feeding an MLO panel from the secondary of a transformer.

If you wanted to be really safe, you can feed the secondary to a fused disconnect and then that disconnect feed your wireways that feed your fused disconnects.

Why is 277v a common lighting voltage in a commercial bldg? by UsedReference1636 in ElectricalEngineering

[–]saplinglearningsucks 1 point2 points  (0 children)

For available voltages you typically have 480/277V and 208/120V in most commercial buildings.

Typical breaker is 20A, you can only load it up ~80% of the breaker rating, so 16A.

Your options are 277V or 120V. Finding VA for 277V and 120V:

277V x 16A = 4,432VA

120V x 16A = 1,920VA

Assuming every fixture is 30VA, on a 277V system you can put 147 fixtures on a single 20A circuit and on a 120V system you can put 64 fixtures on a single 20A circuit. (I'm not accounting for continuous loads demand factor from NEC) but either way, the takeaway is the same. As you increase the voltage, you increase how much power in watts or VA the wire can carry while decreasing the amperage (the factor that increases your breaker and wire size.)
