There seems to be confusion. Is the rear prong configuration a 6-15P or 6-20P going into the wall?

The prongs are plugged in to the existing wall outlet. That's how the timer, when set, controls the power to the device plugged into it.

Yes, on the back (you can't see it in this picture), there are two prongs that pop up and go into the wall socket (for U.S.).

the plugs are adequately spaced so you can fit a regular sized plug side by side. the back has one three prong plug. a downside is that it sits flat against the wall when plugged but see in the middle under plug number two theres a set screw that can be screwed into something but if your wall doesn't have a hole there the screw is useless.

Be careful, it does matter for 120VAC! As with the first contributor, the larger slot is the neutral pole (white), smaller slot is line (black), and the rounded hole is the ground (green). Wiring this incorrectly will either blow a fuse or could subject you to electric shock.

All 6 sockets are 3 prong. Also the back has one 3 prong "active" plug (which is all that's needed to give the unit current); the second plug is three prong but plastic--simply to hold the unit in the wall socket.

Most likely because the typical 120 volt home wall outlet that you would be plugging the surge protector into, is only rated foe 15 amps

With an adapter and the green wire of the adapter grounded to the faceplate screw if it's grounded. This defeats purpose of 6 outlet surge as it would stick out from wall...else have electrician change wall outlet to 3 prong with ground. "Hairy" way is to cut off gnd (U shaped blade) on 6 outlet device and only use it for 2 prong devices which may eliminate surge protection. Considered very dangerous to do this if plugging in devices calling for a ground!!!!

NEMA 6-20p is the plug end. I have found it where you plug in air conditioners, welders, and stand-up coolers

Need to look at the original plug and see if it has two or three prongs. Not where it plugs into wall which should have three, but where that wire plugs into the adaptor.

The wall plug on this is not the flat type. It is a standard 3 prong plug similar in size to an outdoor extension cord.

I think the shipper gives you the choice of a "pig tail" cord or other. We have an older system that has the hose outlet and then the plug beside it so I got the pig tail electrical cord that gives some slack to plug into the wall outlet. I also still have my old power head that I keep downstairs and it hooks up just fine to that it also has the two prong.

Mine is a regular two prong AC wall plug type. It would plug into any U.S. standard 120 volt outlet.

It is a three pronged plug and I believe it must go directly into the wall (not through a power-strip for instance). Check the vendor site for more details.

I don't know if this helps, but I ran a 3 prong male plug from a small refrigerator though it. I had to angle it, but it went through.

It is 3 prong where it goes into the wall. The picture is bad, you are right. It's a very sturdy plug but only good if you don't need to actually adapt the outlet to take 3 prongs instead of 2.

In the owners manual it states. Use wall receptacle: Standard 125V, 3-wire grounding receptacle rated 15A, 125V ACPower supply: Use 15 AMP. time delay fuse or 15 AMP. circuit breaker.

It goes into the Bottom outlet but also covers the top outlet. I thought I was going to have problems with not enough outlets but six is plenty for me
