Frequently Asked Questions
Should Hoffman heaters be placed high or low?
Warm air rises more quickly than cool air. So, for optimal heating, position this heater at lower levels.
What is the difference between an enclosure and a junction box?
Junction boxes are smaller in size than enclosures. Also, enclosures come in different style covers, such as screw cover, hinge with screw cover and hinge with latch cover.
What is the purpose of enclosure?
Enclosures protect electrical equipment in industrial and utility applications. They shield equipment from electromagnetic and radio frequency interference.
