Whole house surge protection

Dracule1,

Why not MOVs?

Some reading material....
Eaton’s Residential Surge Protection
.

I think the whole house surge protectors are made of silicon oxide vasistors, which is suppose to be reusable over and over, unlike MOVs.

Dracule1,

Not sure about that. I believe most are MOV type.

Eaton (Cutler Hammer), Square D, Leviton, and Siemens, use multiple MOVs.

Lissnr,

Where does it say the PS 1200 is a surge protector?

The video says the unit is UL approved. UL 1449 - 3rd addition?

The video with the motor mounted on the board is very misleading.
A squirrel cage induction motor without a connected loaded will have a very poor PF (power factor). The closer the motor is loaded to its rated HP (horse power) the more efficient the motor will be. There in higher PF.

It appears the PS 1200 is nothing more than an AC capacitor that when connected across the AC mains will raise the mains line voltage somewhat.

In the case of a squirrel cage induction motor operated within the motor nameplate data specs an increase in line voltage will result in a decrease in current draw, amps.

P = E x I

P = power measured in watts
E = voltage
I = amps

The Power Utility company meter measures watts consumed. That is why it is called a watt hour meter.

As a residential power user I see no savings gain from using the PS 1200 unit.

Sorry.......

Dracule1,

Which ever external mounted SPD you go with the unit protects best when the wire leads from the SPD are as short as possible.

If possible the breaker used to connect the SPD to the bus of the electrical panel should be installed as close as possible to the load side of the main breaker as well as the neutral/ground bus bar. Inches matter!

Sharp bending of the SPD wire leads must be avoided.

As for the Eaton CHSPT2ULTRA you will notice the manufacture recommends a 2 pole 50 amp breaker be used for connecting the the SPD to the electrical panel bus.

Brickwall ground pin is only connected to this dedicated earthing and nowhere else .

Radni,

Per NEC code the Aux Grounding Electrode you have installed shall connect to the equipment grounding conductor of the branch circuit that feeds the Brickwall and your audio equipment.

What you have now is an isolated grounding electrode that is not electrically connected to the main grounding electrode system of your home. This is a violation of NEC code and the local codes in your area.

Ask your electrician in the event of a ground-fault condition of the Brickwall or associated audio equipment fed by the Brickwall, how the ground-fault current will return back to the source. The source being the electrical panel in your home.

I look forward to his answer......
Jim
