I am building a separate standing shop requiring that i move my home service meter box to a location near the shop (transformer is very close to shop). This requires extending the service line underground from new meter at shop to the location of "old" meter (currently fed by overhead power), which is then channelled underground to the house. Moving the meter box to the shop allows me to eliminate two service poles carrying overhead line that are in the way of the shop. Service is 200 amp Question: Basically I need to "splice" the the new underground line to the existing underground line to the house. What would be better? an underground box with a splice kit (aluminum 4.0 to existing copper 3.0) or an above ground junction box? I would like to have some available power for outside light, etc. at this location, so a box with a few breakers sounds preferable. Any thoughts?

I currently have a 240 V circuit dedicated to a NEMA 10-30 receptacle for a 24 V dryer, with a 30 Amp breaker. I want to add a NEMA 6-50 receptacle for a 48 amp kiln to the same circuit because I have no more room in my panel for a seperate circuit. If I switched out the 30 Amp breaker with a 60 amp breaker and ran a 6 gauge wire from the breaker to the 6-50, how would I reconnect the 10-30 to the circuit? (The 10-30 is currently connected to the panel with an 8 gauge, would I have to replace that wire to match the 6 gauge feeding the 6-50?) I won't be running both devices at the same time. Thanks! Kyle
