Interior electrical equipment used out doors with homema

[TVH]

Construction Contractors can be seen using interior rated circuit breaker panels at exterior locations. These interior panels are enclosed in "homemade" wooden cabinets or shielded from the weather elements using makeshift arrangements. Such arrangements are made for short duration work activity on construction sites. Contractors claim such homemade enclosures meet code weatherproof requirements. Are they correct?

If homemade and unrated wooden cabinets are an acceptable solution, how should they be constructed?

Is a wood frame house anything more than a home-made unrated wooden cabinet? How would one define indoors any differently?

Thank you for the reply.
Are there specifications on how homemade wooden cabinets (containing non weatherproof electrical equipment) should be constructed?

Similarly, in a washdown area, can you hang shower curtains in front of NEMA 1 breaker panels and call it good.

as long as the shower curtains actually prevent water from spraying on the PB, the PB is not subject to getting wet.

so the answer to your question is a qualified yes.

Thank you all for your time in responding to the issue.

So the answer to my question is that any cabinet that keeps the equipment dry is acceptable.

I think any arrangement that keeps the Nema 1 equipment dry is acceptable. I don't think it necessarily needs to be a cabinet even.

A cabinet is conveninet, but a tent would work too.
