Review: Good investment, DIY only if you know electrical or are a careful, thorough learner! - Just installed, so I am relying on its reputation/sales/longevity on the market. The unit is solid, compact, and the 10 g tinned copper wires are impressive. Installation- for simple installations by a pro I would look for $150-$200 MAX. My DIY took over an hour, but I am slow and careful. Do your homework FIRST! Note- double tapping (2 wires under 1 screw) is dangerous and not "Code" unless the fitting is approved for that (never seen that yet!). Use the pigtail method on all 3 connections. Also, screw tightness is now a Code issue and specs are on newer disconnect boxes. Up your DIY "game" and consider getting a torque screwdriver. If your original set-up has white wires being used as "Hot" wires, consider using black tape or heat shrink to properly mark them. (See before and after pix-hot wires are in center. White is reserved for neutral, not hot.) WAGOs are great, but be sure to use the larger 20g-10g ones, as the AG3000 has 10 g wire. I used tape to avoid lever movement with some white adhesive tape on the ground wago. The box gets pretty tight, but it CAN be done properly, in a standard disconnect box. Document (and save) everything as soon as you are done, who knows what you might need to make a claim.

## Questions & Answers

**Q: I have a whole house surge protector installed.  Can I use this intermatic ag3000 hooked at my furnace plus another one at my outdoor ac service?**
A: A whole house surge protector, is primary protection. A furnace surge protector is secondary protection. You need both. The furnace has a sensitive circuit board which can, and I have seen, blow out from a surge. These circuit boards can run about $300 from the HVAC tech, if he/she has one in the middle of the winter. Plus the service call charge.

**Q: Aloha, I don't understand how this works, The wiring looks like its parallel to the equipment it's protecting. How does it protect it?**
A: I placed one at my disconnect box outside by the AC unit. Once you kill the power and remove the cover that hides the wiring, all you do is attach one black wire to each of the incoming hot wires from the house, then connect the green to the ground wire then you have your 220 protected before it reaches your AC unit. to hook it up to your inside furnace you have to twist both black wires together to the incoming hot wire and ground to ground making it a 120 volt surge protector.

**Q: do you need this if you have a whole house surge protector that protect the entire fuse box?**
A: Hello,

It is not required but it is always recommended that you get one to individually protect the outdoor condenser.

**Q: This model AG3000, I would serve to protect 100% of my apartment? or just a line? What model would serve me?**
A: This will protect only the piece of equipment it’s installed on. This device should not be installed on more than 1 piece of equipment, if you have to ask you probably should have one professionally installed.
