Re: Hammond choke 193L installation for dummies?

Its easy...

* If wiring the Hammond 193L choke to a three prong grounded plug:
Use a brass plug. Wire the choke's longest black lead to hot, shorter black lead to neutral and ground the choke using the metal casing to the AC male plug. Any 14ga. or larger three conductor AC rated cable will work. Try to keep the length of the cable as short as possible, like 3' or shorter. Plug the choke into the duplex. Wait at least 5 days to judge or critical listening.

* If wiring directly to a duplex outlet:
Wire the choke's longest black lead to hot, shorter black lead to neutral and ground the choke using the metal casing to either the ground of the duplex outlet or to the main ground point (star ground) of the PLC, power strip, etc. WARNING: be sure to disconnect the power to the duplex outlet before working on it! AC is dangerous, make sure you know what you are doing before experimenting with AC devices.

For grounding to the metal case: First sand with 220 grit or finer sand paper, then polish the metal casing with ProGold (100% preferred) and steel wool where the contact will be. I use a gold plated copper ring purchased from Osh Hardware to attach the ground wire to a bolt of the metal casing on the choke.

Hammond 193L chokes can be purchased at Parts Express. Cost is $35.67 each plus shipping.

Good luck, be safe and have fun.

Best Regards,

Chris
