UL

[wireday]

looking at this timer from intermatic GM40AVE-RD89, The unit says its UL listed,is it ok that a operator can just push the plastic tang to remove the front cover,no tools needed? I dont care for plastic too much.But it seems the way the world is going.

Why do you consider that a problem?

A lot of electrical equipment can be opened without tools.

it would be in a commercial application. I thought tools were needed to access live terminals. could you mention a few of the other examples.

Some, but not all:

Disconnect switches.

Control panels.

Etc.

Shoot, take the bulb out of a desk lamp and you have exposed live parts if it turned on.

The requirement for tool access is in NFPA79, which applies to controls for industrial machinery.

Thank you jraef, that said this timer will be intended for a commercial production machine. The timer is UL listed and the manufacturer states in there instructions commercial/industrial. So would it be ok.

Would someone know the article from NFPA79 ?

I located NFPA79 6.2.3.2

Thats a good point Jumper. This is a manufacturing plant, The machine makes the product.Does NFPA79 cover that as well ?

I found this,

purpose commercial applications. The control operates on any AC voltage from 120 VAC to 277 VAC.
