Questions and Answers for GE PowerMark Plus Outdoor 70 Amp 2-Space 4-Circuit Single-Phase Main Lug Circuit Breaker Panel

A:  'Top or bottom' continued..... After studying the pictures and descriptions , I do think it would be very easy to flip the buss assembly, *** However it would be very, very difficult to get the dead front to fit the circuit breakers decently. Guess I will need to get a few split bolts and a few feet wire, to extend the feed wires coming from the bottom so they reach the lugs, at the top of the panel. ( Use split bolts to splice the wires if you do not have a large crimper. )

A:  So after studying this panel it is not possible to flip the bus bar assembly, I must extend my existing bottom feed wires to reach the lugs at the top. Home Depot does have some set screw type wire couplings that should work to add the extra needed wire length, at a reasonable price.

A:  You would have to attach at least four clips with tapped holes for the panel screws. I recommend using In-Line Splice Kits to extend the wires instead to avoid voiding the UL on the panel.

A:  Reply to Sparky : Thank you for your response. This is being used as a 100 amp sub-panel with a 100 amp breaker feeding from the Main Service Entrance. However the original installer used 3/0 copper, which is more than a little "over-sized" ! That is hard enough to bend normally, but when you add a splice, crimped or set screw type, it locks the strands from flexing, there by making the 3/0 copper even harder to bend. My current tool inventory only includes a crimper that goes up to number one AWG. Then add enough tape for a safe long term splice, there will be some large 'eggs' on these conductors. So while "splicing/extending" is one option, I would like to avoid that, if possible.

A:  So... Turning the buss assembly top lugs down looks relatively simple, HOWEVER the dead front breaker cover would NOT ever fit proper ! *** NO CHOICE but to extend my existing bottom feed wires.

A:  There is no item number for a "200" amp breaker in a "125" amp panel! The most you can put is a 125 amp breaker.

A:  Thank you for your question. The size wire depends on many factors, the length of the run, wire type, etc.

A:  I would encourage you to look up an ampacity chart readily available online to confirm your individual situation. If using romex or UF cable #4 would carry 70 amps under normal conditions. The temperature and length of run may change that so please confer with a qualified electrician or professional engineer to confirm. Thanks for the question.

A:  Thank you for your question. Yes, the TL270RCUP will accept 2pole 40a breakers THQL2140 or THQP240.

A:  This is not a sub-panel, It is a Disconnect box for that purpose only. Used in HVAC mostly. Once is awhile they fail. ! out of 10,000.

A:  Make sure that you add di-electric grease to the lugs, wire ends, and breaker contacts. It can be messy and the reasons to do so are not obvious until you get to a corrosion failure. The grease is available at home depot, but you may have to ask for help. I have had quite a few breakers and a several panels fail in San Francisco where the long term effects of being near the ocean accelerates the corrosion on outdoor panels that are miles from the ocean. Use the grease to prevent this long term problem.

A:  Thank you for your question. The TL270RCUP main lugs accept #6 to #3 AWG wire.
