Square D AL150HD – Frequently Asked Questions
1) What wire sizes will the Square D AL150HD lug kit accept?
The AL150HD mechanical lug kit takes 14 AWG through 3/0 AWG conductors, and it is rated for either aluminum or copper wire. That range covers the full 15A to 150A span of the PowerPacT H breakers it is made for, so one kit handles a feeder at 150A or a small branch run at 14 AWG.
2) Will the AL150HD lugs fit a Square D PowerPacT H breaker larger than 150A?
No. The AL150HD kit is specified for PowerPacT H breakers in the 15A to 150A range, with a 14 to 3/0 AWG wire range. For a frame above 150A you need the lug kit matched to that breaker's amperage, not this one.
3) How many lugs come in the Square D AL150HD kit, and is one kit enough for a 3-pole breaker?
Each AL150HD accessory kit contains three lugs, which is one per pole on a 3-pole PowerPacT H breaker. The kit is configured for 3P. If you are terminating both line and load ends, you need two kits per breaker. The kit is packaged as a set of 4.
4) Do I need to order lugs separately for a unit-mounted PowerPacT H breaker or an I-Line breaker?
On unit-mounted M-frame and P-frame breakers, lugs come standard on both ends, so added lug kits are usually only for replacement or for changing wire range. On I-Line configurations, lugs are standard on the off end only, since the line side plugs onto the bus, so the AL150HD covers the load side termination.
5) Is an ABB XT4 front terminal kit a substitute for a Square D PowerPacT H aluminum lug kit?
No. The ABB KXT-3PC is a 3-piece front terminal kit for copper-aluminum cable on ABB XT4 frame breakers, and the Square D AL150HD mechanical lug kit is dimensioned for PowerPacT H breakers in a 3-pole configuration. Both terminate copper or aluminum conductors, but terminal kits are frame-specific hardware - an XT4 kit will not land on a PowerPacT H breaker and vice versa.
6) Will a terminal cover or shield do the same job as the Square D AL150HD lug kit?
No - those are different parts. The ABB KXT-HTC3 is a 3-pole high terminal cover for XT4 breakers, the ABB KXT2LTC-3 is a 2-piece set of low terminal covers for 3-pole XT2 breakers, and the Eaton EFTS3K is a three-pole terminal shield for Series G. All three are insulating shrouds that enclose an already-made termination. The Square D AL150HD is the termination itself: three mechanical lugs per kit that clamp 14 AWG to 3/0 AWG aluminum or copper conductors to a PowerPacT H breaker. If you need both protection and a landing point, the lug kit is what makes the connection.
7) What torque do the Square D AL150HD lugs get tightened to?
For 2.5 to 6 mm2 conductors (14 AWG through 10 AWG), the tightening torque is 5 N.m. Use a calibrated torque driver on aluminum conductors in particular, since an under-torqued aluminum termination is the usual cause of a hot lug.
8) Can I use the AL150HD aluminum lugs with copper conductors?
Yes. The lug body is aluminum, but the kit is listed as a mechanical lug terminal for aluminum or copper wire connection, so copper conductors inside the 14 to 3/0 AWG range are an accepted use.
9) Is the Square D AL150HD lug kit approved for commercial and industrial panel work?
The AL150HD kit is UL Listed and CSA certified to UL and CSA standards, which is what an inspector looks for on a panelboard or switchboard termination. It is made in the United States.
10) Do these lugs come with a terminal shield or cover for the exposed connection?
No. The AL150HD is the mechanical lug kit only, three lugs, with no insulating shield. Terminal covers are a separate accessory, and on other platforms they are ordered as their own item, for example the Eaton Series G three-pole terminal shield or the ABB XT4 high terminal cover for 3-pole. If your installation needs the terminals shielded, order that cover alongside the lugs.
11) Which end of the breaker do the AL150HD lugs land on?
The connection location is downstream, so these mount at the load side of the PowerPacT H breaker. On an I-Line panel that is the only end you terminate, because the line side plugs directly onto the bus.
12) For an institutional spec that calls for UL and CSA listed breaker terminations, how does the Square D AL150HD compare with the Eaton Series C terminal kit?
The Square D AL150HD mechanical lug kit is UL Listed and CSA certified, built in the United States, and rated for 15A to 150A PowerPacT H breakers with aluminum lug bodies accepting 14 AWG to 3/0 AWG copper or aluminum. The Eaton 3TA225FD is a pressure-type line and load terminal kit rated 225A for Series C breakers, also suited to copper or aluminum conductors. The deciding factor is the installed breaker family and the ampacity of the feeder, not the terminal kit alone.
13) I need a smaller wire range than the Square D AL150HD for a copper-only feed - what terminal kit covers that?
The ABB KXT1CU-3PC front terminal kit is specified for copper cables from 14 AWG to 1/0 AWG on ABB XT1 frame breakers, a copper-only, narrower range. The Square D AL150HD goes up to 3/0 AWG and takes either aluminum or copper on PowerPacT H breakers, so choose by which breaker frame is in the panel first, then by conductor size.
14) How much room do I need in the gutter for these lugs?
Each lug measures 1.4 in high, 0.874 in wide and 0.765 in deep. Add the bending radius of 3/0 aluminum on top of that when you are checking wire-bending space in a tight panelboard gutter.
