30A 3-Terminal Heavy Duty Junction Box Black is rated 4.3 out of 5 by 43.
Rated 1 out of 5 by from Bad batch... They do look the part. Terminal grub screws are the main problem, the screwdriver slot it poorly formed, not deep enough, too wide. So bad I couldn't back the grub screws out. Tightening was too vague. Terminals also push out the back unless the box is fixed before wiring. Took them back, and used Wagobox and 222 connectors I already had.

Rated 1 out of 5 by from Very Bad Junction Boxes DO NOT PURCHASE THESE JB . The screw terminals are zinc coated steel , not Brass they will start to corrode very quickly , I have fitted some of these in my Double Garage about 6 months back , ,needed to take another feed from one opened up ( had been sealed outside with siicone ) screw had corrosion on them , so I am looking at trying to get some Brass screws now to replace the steel ones ( 5x3 ) or will have to replace the whole JB's .

Rated 5 out of 5 by from Good Solid Junction Box A good solid junction box. Screw terminals that give confidence to really "tighten down" and not worry about the brass connectors or the plastic mounting columns giving way. Well worth a few coppers more for the HD box.
