Connectors and cables

Connectors and cables which connect directly to the eGauge meter.

2-pin CT Plug

 Visit the online store page

Original manufacturer part number: Tyco model 284506-2

Do not connect unsupported sensors to eGauge meter inputs or damage may occur.

2-pin Plug

Sensor port connector with 2 positions. Accepts one positive and one negative wire. Used to connect CTs and supported sensors to the eGauge, as well as DC voltage to the EG4xxx DC input. Replacement component for eGauge meters.

Hardware included

Assembly/installation information

The two-pin plug is secured to the ends of a sensor lead for connection to the eGauge. May also be wired to DC output to power and/or take DC voltage measurements to the EG4xxx DC voltage input.

Suggested screw torque for the 2-pin plug is 2.7 in.-lb.

Power Whip (208V or 277V)

 Visit the online store page
SKU: Power Whip

The Power Whip is an installation component used to connect the eGauge meter to a breaker panel.

Each Power Whip includes a 5-pin Power Plug and four 8’ lengths of THHN #12 stranded copper wire for Neutral, L1, L2 and L3.

Available in 208V (white, black, red blue) and 277V (white, yellow, orange, brown).


eGauge Power Whip


Assembly/installation information

The 5-pin power plug is connected to the 4 segments of wire with heat shrinking at the base. Trim the wire segments to length and connect the appropriate colors to the correct breaker and neutral connections. Insert the 5-pin power plug to eGauge when complete.

If the 208V whip is used on a single-phase 208V or 240V system, the blue wire (L3) should be removed from the whip assembly.

eGauge 5-pin power plug

Twisted Pair Wire

 Visit the online store page

18ga black and white twisted pair wire for extending CT leads or other signal wiring. Twisted pair wire is 18 AWG rated at 600V. Wire is sold without connectors or other hardware.

CTs may also be extended without splices or soldering using the eGauge Sensorhub as a CT extension kit.

If extending CTs, do not use wire nuts to connect extensions. Wire nuts will degrade and interfere with the low-voltage CT signals.


Hardware included

Assembly/installation information

For extending CT leads:

  1. Remove the existing 2 pin CT plug from the CT lead.
  2. Splice in the required length of twisted pair wire. Soldering the splices is recommended (butt splice connectors are a secondary option).
  3. Reattach the 2 pin CT plug. Ensure the polarity on the plug is correct.

5 Pin Power Plug

 Visit the online store page

Current manufacturer information: Adam Tech EBH-05-G

Voltage terminal connector block with 5 positions. Accepts three line voltage conductors (L1, L2, and L3) and a neutral conductor. Split-phase installations use the L1, L2, and N terminals. Single phase installations use the L1 and N terminals.

This is a replacement part for eGauge meters. Every eGauge meter includes a 5-pin plug with it.

eGauge 5-pin Power Plug

Hardware included

Assembly/installation information

Connect appropriate voltage measurements to the screw terminals and tighten securely. Do not connect anything to the "Unused" terminal. If wiring a single-phase system, leave the L3 terminal unused. 

Suggested torque for the 5-pin power plug is 5 in.-lb.

Test Power Cable

 Visit the online store page

Test Power Cable for EG4xxx (Core/Pro) Meters (with international adatpers).
This cable may be used to power the eGauge for pre-install configurations, to obtain data from an eGauge after being removed from an installation, or can be used to power the eGauge if AC power or voltage measurements are not needed.

When measuring AC power, the AC voltage inputs must be utilized, power cannot be calculated otherwise. The Test Power Cable may be used to power an eGauge while it is measuring high voltage, but the AC inputs (L1/L2/L3/N) must be connected to the system being monitored.


eGauge Test Power cable




The test power cable may only be used with EG40xx meters (Core and Pro).

The test power cable is suitable for testing and programming an eGauge, and cannot be used when measuring power.

The test power cable is rated for 120-240Vac. It cannot be connected to higher input voltages.

Assembly/installation information

The test power cable must be connected to the Ldc terminal. If connected to a Sensor/CT input damage may occur

  1. Select the appropriate receptacle adapter.
  2. Clip the receptacle adapter into the body of the power supply.
  3. Connect the two pin plug to the Ldc terminal (next to the five pin power plug.
